Frequently Asked Questions
Q: What are the specifications of bearing assembly 220038027?
A: Bearing assembly 220038027 is a deep groove ball bearing with 20 mm bore, 47 mm outer diameter, and 14 mm width. It is constructed from SAE 52100 chrome steel with double seals, a pressed steel retainer cage, and precision-ground surfaces with Rockwell C58-C62 hardness.
Q: Which pallet jack models and load ratings is bearing 220038027 designed for?
A: Bearing assembly 220038027 is designed for manual pallet jacks rated up to 5500 lbs. It fits load wheel hubs on pallet jacks from Crown, Toyota, Raymond, Yale, and other OEM manufacturers using 20 mm bore hubs. Verify your jack model and load capacity before ordering.
Q: What does press-fit installation mean for bearing 220038027?
A: Press-fit installation means this bearing is designed to be pressed directly into a pallet jack wheel hub with an interference fit. The hub bore is manufactured to close tolerances to ensure the bearing stays secure under the radial and thrust loads generated during lifting and rolling.
Q: Why are the seals on bearing 220038027 important?
A: The double seals on bearing assembly 220038027 protect the bearing balls and races from contamination, moisture, and debris. Sealed bearings require less maintenance and provide longer service life in wet, dusty, or cold storage environments where pallet jacks operate.
Q: How long will bearing assembly 220038027 last under normal pallet jack use?
A: Under normal operating conditions, bearing assembly 220038027 typically lasts 5 to 10 years. Lifespan depends on load frequency, maintenance practices, environmental conditions, and proper lubrication. In heavy-use or harsh environments, replacement may be needed sooner.
Q: What material properties make SAE 52100 chrome steel suitable for this bearing?
A: SAE 52100 chrome steel is a high-carbon bearing steel that provides exceptional hardness, wear resistance, and fatigue strength. The Rockwell C58-C62 hardness specification ensures the bearing races and balls can withstand repeated stress cycles from thousands of lift-and-lower operations without deformation or spalling.
