Mast Bearing for Forklift

Frequently Asked Questions

Q: What type of bearing is the 105475 mast bearing?
A: The 105475 is a precision guide roller bearing used in mast carriage assemblies of electric lift trucks. This bearing supports both radial and thrust loads in vertical mast applications, typical for equipment from Crown, Toyota, Raymond, and other major OEM brands.

Q: What materials and construction does this mast bearing use?
A: The 105475 features hardened bearing steel construction designed for high-load industrial duty. The bearing is built with precision-ground inner and outer races to maintain alignment and reduce wear on mast guides.

Q: How do I know when to replace the 105475 bearing?
A: Replace the bearing if you hear grinding, squeaking, or rattling from the mast assembly during vertical travel. Visual inspection may show wobbling of the mast, uneven wear on guide rails, or debris around the bearing area. These symptoms indicate bearing degradation or cage damage.

Q: What is the load capacity of the 105475 mast bearing?
A: Load capacity depends on bearing design and preload. The 105475 is engineered to handle typical radial loads from mast carriage weight and loads stacked on forks. Verify your specific truck model weight rating matches this bearing specification.

Q: Does the 105475 replace any other bearing part numbers?
A: The 105475 is a cross-reference equivalent for mast bearings used across multiple electric lift truck models. Confirm your equipment model, serial number range, and bearing location match before ordering this replacement.
