Wholesale Thrust Spherical Roller Bearing

Wholesale Thrust Spherical Roller Bearing Manufacturer

Shanghai Yinin Bearing & Transmission Company is a wholesale thrust spherical roller bearing manufacturer and supplier based in China. Since 1999, we have evolved from representing domestic bearing brands to operating an integrated sales and manufacturing group, including Jiangsu Dahua Bearing Manufacturing Co., Ltd. Our thrust spherical roller bearings are designed for applications that demand high axial load capacity, self-alignment, and reliability under severe operating conditions.

We supply four main series—29200, 29300, 29400, and large-size custom designs—each engineered to meet specific load and speed requirements. Our factory in Jiangsu Province uses precision grinding and heat treatment processes to deliver bearings that meet international dimensional and material standards. With a dedicated team of 12 technicians and a quality control system that inspects at every stage, we support OEM, replacement, and project-based procurement.

Our Thrust Spherical Roller Bearing Range

Thrust spherical roller bearings are unique in their ability to accommodate heavy axial loads while allowing for angular misalignment. They consist of a shaft washer, housing washer, and a set of barrel-shaped rollers guided by a cage. The spherical raceway on the housing washer enables self-alignment, compensating for shaft deflection and housing deformation.

Each series is available in standard and custom configurations. We can adjust the cage design, internal clearance, and heat treatment to suit your specific operating environment. Our engineering team works with you to select the correct series based on equivalent dynamic load, speed factor, and lubrication method.

Application Fit and Engineering Value

Thrust spherical roller bearings are used in vertical and horizontal shaft arrangements where axial loads are dominant and misalignment is possible. Common applications include:

• Heavy-duty gearboxes and transmissions
• Hoisting and material handling equipment
• Marine propulsion and rudder systems
• Mining and construction machinery
• Wind turbine pitch and yaw systems
• Steel mill and rolling equipment

Our bearings are manufactured from high-grade alloy steel, with heat treatment that ensures hardness and fatigue resistance. We apply precision grinding to achieve tight tolerances on bore, outside diameter, and height, ensuring consistent performance and easy mounting. For applications with high vibration or shock loads, we can supply reinforced cages and special internal geometries.

Critical Specifications and Selection Criteria

When configuring a thrust spherical roller bearing, the following parameters are critical:

• Axial load rating: Static and dynamic load capacities must exceed the applied forces.
• Speed rating: Thermal speed limits depend on cage type and lubrication.
• Shaft and housing fits: Proper interference fits prevent ring rotation and wear.
• Misalignment tolerance: The bearing can accommodate up to 1.5° to 2° of static misalignment, depending on series.
• Lubrication: Oil or grease; we can specify suitable methods for high-temperature or high-speed operation.

Our proposal includes a detailed specification sheet with dimensions, load ratings, and limiting speeds. We also provide mounting recommendations and installation guidelines to ensure correct preload and alignment.

Quality Assurance and Testing

Quality is integral to our manufacturing process. Each production stage—from raw material inspection to final assembly—is subject to inspection. Finished bearings are tested for dimensional accuracy, radial and axial runout, and noise/vibration levels. We can perform full inspections according to your specifications or international standards such as ISO 492 and GB/T 307.1.

Our factory is equipped with precision measuring instruments and testing equipment, allowing us to verify critical characteristics like raceway profile, surface finish, and hardness. For high-volume orders, we implement statistical process control to maintain consistency.

Customization and Project Support

We understand that standard catalogs do not always cover every requirement. Our engineering team can customize thrust spherical roller bearings in terms of:

• Dimensions (bore, OD, height) for non-standard shafts
• Materials (e.g., stainless steel for corrosive environments)
• Cage types (machined brass, steel, or polyamide)
• Heat treatment and surface coatings
• Special packaging for export

We also offer technical support during installation and commissioning. Our team can provide training for maintenance staff on proper mounting, lubrication, and condition monitoring. For large projects, we coordinate logistics to ensure timely delivery to your site.

Information We Use to Configure Your Solution

To prepare an accurate quotation and technical proposal, please provide the following details:

• Bearing series or reference number (if replacing an existing bearing)
• Shaft diameter and housing bore dimensions
• Axial and radial loads (magnitude and direction)
• Operating speed (RPM)
• Operating temperature range
• Lubrication type (oil or grease) and method
• Misalignment or shaft deflection expectations
• Required tolerances or special materials
• Quantity and delivery schedule

With this information, we can recommend the most suitable series and configuration, ensuring optimal performance and service life.

Packaging and Delivery

All bearings are individually packaged to prevent corrosion and damage during transit. Standard export packaging includes rust-proof oil, wrapping paper, and wooden or carton cases. We offer various delivery terms (FOB, CIF, etc.) and can arrange sea, air, or express shipping. For urgent requirements, we maintain stock of popular sizes and can ship within 3 working days.
