81106M Thrust Roller Bearing 30x47x11 mm with Brass Cage

If you are selecting a thrust roller bearing for heavy axial loads, you need more than a standard bearing size. You need a design that can maintain axial positioning, withstand demanding loads, and operate reliably in your equipment. The 81106M thrust roller bearing from Shenzhen Xinchangsheng Bearing Co., LTD. (XCCZC Bearing) uses cylindrical rollers and a robust brass cage to support high unidirectional axial loads. With a 30 mm bore, 47 mm outside diameter, and 11 mm total height, this bearing fits compact axial-support applications where load capacity and rigidity matter. You can consider it for vertical pumps, gearboxes, crane mechanisms, injection molding equipment, and other industrial machinery operating at low to moderate speeds.

81106M Thrust Roller Bearing Specifications

The 81106M belongs to the ISO 81100 series of single-direction cylindrical thrust roller bearings. Its cylindrical rollers create line contact with the raceways, allowing the bearing to handle substantial axial forces while maintaining a compact envelope.

Key Technical Data

  • Bearing model: 81106M
  • Bearing type: Single-direction cylindrical thrust roller bearing
  • Bore diameter (d): 30 mm
  • Outside diameter (D): 47 mm
  • Total height (T): 11 mm
  • Cage: Precision-machined brass cage
  • Material: High-carbon chrome bearing steel
  • Tolerance: Normal / P0 class
  • Load direction: Unidirectional axial load
  • Operating range: Low to moderate rotational speeds

The brass cage helps maintain roller spacing and guidance during operation. Meanwhile, precision-ground and lapped surfaces help provide consistent contact between the rollers and raceways.

Why Choose This Cylindrical Thrust Roller Bearing?

When your equipment generates significant axial force, a thrust roller design can provide a practical alternative to a thrust ball bearing. The cylindrical rollers provide line contact rather than point contact, supporting higher axial loads within a similar compact configuration.

High Axial Load Capacity

The 81106M is designed specifically for high axial loads. This makes it suitable when your application requires reliable thrust support rather than primarily radial load handling.

High Rigidity

Under heavy axial loading, the bearing helps maintain stable axial positioning. This characteristic is useful for equipment where excessive axial deformation could affect alignment or mechanical performance.

Brass Cage Construction

The precision-machined brass cage guides the cylindrical rollers and maintains consistent spacing. For demanding industrial applications, this construction can contribute to stable roller movement and reliable operation when appropriate lubrication is maintained.

Compact 30x47x11 mm Configuration

With dimensions of 30x47x11 mm, you can use the 81106M where installation space is limited but substantial axial support is still required.

81106M vs. Thrust Ball Bearing

Before selecting your bearing, you should compare the load characteristics and operating requirements of each design.

Where Can You Use an 81106M Thrust Roller Bearing?

You can integrate this heavy duty thrust roller bearing into equipment where axial forces need controlled and reliable support.

Typical applications include:

  • Vertical pumps: Supports axial forces generated during pump operation.
  • Gearboxes: Helps locate components against axial thrust generated by helical or worm gears.
  • Crane and lifting equipment: Provides axial support in heavy-duty mechanisms.
  • Injection molding machines: Supports axial loads in clamping and mechanical systems.
  • Industrial presses: Handles substantial axial forces during pressing operations.
  • Agricultural and construction equipment: Supports pivot and axial-load components.

Before installation, you should confirm the actual axial load, shaft and housing dimensions, speed, lubrication method, operating temperature, and required clearance.

How to Select the Right 81106M Bearing

Follow these steps before placing an order:

  1. Confirm the dimensions: Check that the 30 mm bore, 47 mm outside diameter, and 11 mm height match your assembly.
  2. Calculate the axial load: Determine the continuous and peak thrust loads generated by your equipment.
  3. Check operating speed: Make sure the expected rotational speed is suitable for a cylindrical thrust roller design.
  4. Review lubrication: Select an appropriate grease or oil based on speed, temperature, and operating conditions.
  5. Confirm clearance requirements: Standard clearance may work for many applications, while special preload or thermal expansion conditions may require modified specifications.
  6. Discuss customization: Contact the manufacturer if you require different dimensions, clearances, packaging, or OEM specifications.
