Frequently Asked Questions
Q: What are the exact specifications for bearing assembly 805111-5?
A: Part 805111-5 is a manual pallet jack sealed ball bearing assembly with the following specifications: 20 mm bore, 47 mm outer diameter, 14 mm width, Grade 10 precision steel balls, double nitrile seals, chrome steel construction, and factory pre-lubrication. Dynamic load rating is 16.6 kN. Static load rating is 9.75 kN. Maximum speed rating is 8000 RPM under grease lubrication.
Q: What equipment is the 805111-5 bearing assembly compatible with?
A: Part 805111-5 is designed for manual pallet jack wheel support in non-powered pallet truck applications. It fits standard manual pallet jack wheel kits across Crown, Toyota, Raymond, Yale, and similar brands where bearing bore is 20 mm and outer diameter is 47 mm. Confirm your wheel dimensions and bore configuration before ordering.
Q: What are the material and hardness specifications for 805111-5?
A: Part 805111-5 uses chrome steel construction with Grade 10 precision steel balls. Raceway and ball hardness is Rockwell C58 minimum, which provides durability under the load cycles typical of manual pallet jack operation. Double nitrile seals protect against moisture and contamination in warehouse environments.
Q: What is the expected lifespan and maintenance schedule for bearing 805111-5?
A: Manual pallet jack bearings like 805111-5 typically last 4 to 6 years under normal warehouse use with regular operator lubrication. Bearing life depends on load, frequency of use, and environmental conditions. Inspect bearings annually for noise or resistance. Replace if grinding sounds develop or bearing rotation becomes stiff. Re-lubrication may extend life if bearing is disassembled and inspected for wear.
Q: Is bearing 805111-5 pre-lubricated, or does it require lubrication at installation?
A: Part 805111-5 comes factory pre-lubricated with grease. No additional lubrication is required before use. The bearing is sealed with double nitrile seals to retain the factory grease and exclude moisture and dirt during storage and initial operation in typical warehouse conditions.
Q: What is the maximum speed rating for bearing 805111-5?
A: Part 805111-5 is rated for a maximum speed of 8000 RPM under grease lubrication. Manual pallet jacks typically operate at wheel speeds far below this limit, so RPM rating is not a constraint for standard pallet truck use. Speed rating is relevant only in high-speed conveyor or special-application equipment.
