Raymond Thrust Bearing for Pallet Jacks

Frequently Asked Questions

Q: What is the RA 671-012-04 and what role does it play in a caster assembly?
A: The RA 671-012-04 is a thrust bearing engineered for electric pallet jack and walkie lift truck caster assemblies. It is designed to handle axial loads generated when the caster swivels under load. The bearing mounts within the caster assembly on Raymond 8300, 8400, and 8500 series equipment, supporting the wheel spindle and allowing smooth, controlled swivel motion.

Q: What are the key dimensions of the RA 671-012-04?
A: The RA 671-012-04 features ... These dimensions are critical for proper fit within Raymond caster assemblies. Cross-reference part numbers include RA67101204 and 67101204.

Q: What material is used in the RA 671-012-04?
A: The RA 671-012-04 is constructed from high-carbon bearing steel, a material engineered 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: What signs indicate the RA 671-012-04 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 worn and requires replacement.

Q: What is the typical service life of the RA 671-012-04?
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.
