Frequently Asked Questions
Q: What is the RA 671-012-04 thrust bearing and what role does it play in the caster assembly?
A: The RA 671-012-04 is a thrust bearing engineered for electric pallet jack and walkie lift truck wheel assemblies. It is designed to handle axial loads (forces pushing along the axis of rotation) generated when the caster swivels under load. The bearing mounts within the caster assembly on Raymond 8300, 8400, and 8500 series trucks, supporting the wheel spindle and allowing smooth swivel action.
Q: What are the dimensional specifications for the RA 671-012-04 thrust bearing?
A: The RA 671-012-04 thrust bearing features a 0.98 inch inner diameter and 2.04 inch hub inside diameter. These dimensions are critical for proper fit within the Raymond caster assembly. Always verify bearing bore and mounting surface dimensions match your caster application before ordering. Cross-reference part numbers include RA67101204 and 67101204.
Q: What material is the RA 671-012-04 thrust bearing made from?
A: The RA 671-012-04 is constructed from high-carbon bearing steel, a specialized material designed to withstand repeated stress and maintain tight tolerances. High-carbon bearing steel resists deformation, provides consistent rolling element guidance, and delivers reliable performance under the oscillating axial loads typical of caster swivel motion.
Q: How do you know when the RA 671-012-04 thrust bearing needs replacement?
A: Signs of thrust bearing wear include grinding or rough noise when swiveling the caster, difficulty rotating the caster wheel assembly, increased resistance to swivel motion, or play or looseness at the caster base. If caster movement becomes jerky, noisy, or requires excessive force to swivel, the bearing has likely failed and requires replacement.
Q: What is the typical service life of the RA 671-012-04 thrust bearing?
A: Under normal warehouse conditions with proper maintenance and lubrication, the RA 671-012-04 thrust bearing typically lasts 2 to 5 years. Heavy-duty use, inadequate lubrication, contamination, or rough floor surfaces accelerate wear. Regular inspection for smooth swivel action, absence of noise, and proper grease levels helps extend bearing life and prevent premature failure.
