WIB Bearings

WIB excels in engineering ball bearings and tailor-made sub-assemblies that go far beyond standard catalog products. Our team of design, application, and manufacturing engineers works closely with customers to translate complex requirements into robust, high-precision solutions.

From performance bearings to complete assemblies, WIB  supports a wide range of applications across robotics and automation, food and beverage processing, medical and dental equipment, textile machinery, linear guidance systems, sports and high-speed equipment, home design, packaging, electric motors, welding systems, wire guides, and tooling. WIB products are designed to tight tolerances to deliver low noise, smooth operation, and long service life while maintaining the compactness, reliability, and performance that modern systems require.

History of WIB Bearings

Since its founding in 1961, WIB Bearings has been a benchmark manufacturer in the Swiss precision engineering landscape. From Bulle, in the heart of Switzerland, the company has built a reputation for producing high-precision ball bearings and sub-assemblies that meet stringent industrial standards.

Today, WIB exports around 90% of its production to customers worldwide, with approximately 70% delivered across Europe, 20% to overseas markets, and 10% to Switzerland.

This international footprint is supported by continuous investment in R&D, state-of-the-art equipment, and advanced process control. Collaborations with leading Swiss universities keep WIB at the forefront of innovation in motion technology, enabling the development of new materials, heat treatment, and designs for next-generation bearing solutions.

Backed by ISO 9001 and ISO 14001 certifications, WIB combines Swiss craftsmanship with responsible manufacturing practices, reinforcing the trust it has earned from OEMs and engineering companies across more than six decades.

Product Range and Services

WIB Bearings offers a wide portfolio of performance bearings and engineered solutions, from standard single-row units to highly customized sub-assemblies. Our portfolio includes single and double-row radial and angular contact bearings, self-aligning bearings, thin-section bearings, track rollers, Gothic-profile bearings, and other specialized designs.

Each solution can be tailored through industry-specific variables such as bearing steel or stainless steel grades (including our advanced SP Series), cages, seals, special coatings, heat treatment, lubrication, ceramics technology, noise requirements, and internal geometry. This configurability allows WIB to optimize load capacity, running accuracy, corrosion resistance, and lifespan for each application.

Single Row Radial Ball Bearings

WIB single row radial ball bearings are designed for applications that require smooth rotation, low noise, and low friction under predominantly radial loads with the ability to handle moderate axial loads. They are available in numerous sizes and configurations and can be adapted with special cages, sealing arrangements, and lubricants to match high-speed, high-temperature, or contaminated operating environments.

Double Row Angular Contact Bearings:

WIB double row angular contact ball bearings are engineered to manage combined radial and axial loads in both directions with high rigidity and precision. Building on WIB ACBB expertise, these bearings offer improved load distribution and stability, making them ideal for gearboxes, pumps, transmission systems, robotics, and other high-performance machinery where reliability and efficiency are critical.

Premium materials such as stainless steel, ceramics, and advanced polymers can be specified to enhance speed capability, wear resistance, and service life in demanding duty cycles.

Self-Aligning Bearings

Self-aligning bearings from WIB are designed to compensate for misalignment between the shaft and housing caused by mounting inaccuracies or shaft deflection. Their internal geometry enables smooth, low-friction operation even when misalignments occur, protecting surrounding components and maintaining system stability. Available across a wide range of bore diameters and configurations, these bearings are suited for industrial applications where reliability under varying conditions is essential.

Single Row Track Rollers

WIB single row track rollers are robust solutions for linear motion and tracking applications. Designed with high load-carrying capacity and reliable rolling performance, they are widely used in conveyor systems, linear guides, and automated handling equipment. Their geometry, materials, and surface treatments can be adjusted to match specific track profiles, speeds, and environmental conditions, ensuring low wear and consistent guidance over long operating periods.

Double Row Track Rollers

WIB double row track rollers deliver enhanced load-bearing capability and stability for heavier-duty tracking systems. They are particularly effective in wire-guiding and straightening applications, where durability and precise guidance are essential.

WIB’s latest generation of wire-guides and straightening rollers features an optimized open U-profile and a new high-hardness steel alloy. This combination dramatically reduces wear on the outer ring profile and extends service life. Tests have shown a lifetime more than 15 times longer than the previous V-profile design under identical conditions.

For even more demanding environments, premium material options such as ceramic configurations are available. This includes:

• Technical Support: WIB Bearings offers expert advice and assistance to help customers select the most suitable bearings for their specific applications.

• Custom Solutions: Understanding that every industry has unique needs, WIB Bearings specializes in providing customized bearing solutions tailored to specific application requirements.

• Quality Assurance: Each bearing undergoes rigorous testing and validation as part of WIB’s Design Verification Plan and Report (DVP&R), ensuring they meet the highest standards of quality and performance.

• After-Sales Service: WIB Bearings provides exceptional after-sales support, ensuring that their products continue to perform optimally throughout their lifecycle.

ADVANCED MATERIALS – SP SERIES STAINLESS STEEL (OPTIONAL TEXTBLOCK IF YOU WANT TO HIGHLIGHT IT)

For applications exposed to high humidity, saline atmospheres, or aggressive cleaning processes, WIB offers its proprietary SP Series stainless steel. Developed by our R&D team, this grade combines a nitrogen-based surface hardening process with optimized heat treatment to provide significantly higher corrosion resistance than conventional bearing steels such as AISI 440C while maintaining excellent wear resistance and fatigue strength.

Neutral salt-spray testing in accordance with ISO 9227 showed no visible corrosion on SP Series specimens after 120 hours, in stark contrast to heavily corroded samples made from standard stainless steel, demonstrating the suitability of SP Series for corrosive environments.

SERVICES AND ENGINEERING SUPPORT

WIB is committed to providing comprehensive technical support and engineering services to ensure each customer receives the best solution for their specific application:

• Technical Support & Application Engineering – Expert advice on bearing selection, dimensioning, and operating conditions, including thermal, speed, load, and lubrication analysis.
• Custom Bearing Solutions – Co-engineering of customized designs with adapted materials, profiles, cages, seals, and coatings to improve service life, sealing performance, compactness, or weight.
