Frequently Asked Questions
Q: What are the exact dimensions of SKU 220050996?
A: SKU 220050996 has a 20 mm inner diameter, 47 mm outer diameter, and 14 mm width. These dimensions are standard for load wheel bearings in manual pallet jacks. The bearing is designed for press-fit mounting directly into wheel hubs without machining.
Q: What manual pallet jack models fit SKU 220050996?
A: SKU 220050996 is compatible with Lift Rite and Wesco manual pallet jack models that use 20 mm x 47 mm x 14 mm wheel hub bearings. Before ordering, verify your jack model and wheel assembly dimensions to confirm this bearing is the correct replacement.
Q: What does the 2RS seal designation mean on SKU 220050996?
A: 2RS means this bearing has rubber seals on both sides of the bearing races. These seals protect the raceway and rolling elements from moisture, dust, and warehouse contaminants, extending bearing life in wet floors and cold storage environments. The seals are not removable.
Q: What material are the raceways and rolling elements in SKU 220050996?
A: SKU 220050996 is constructed from precision-ground high carbon chromium steel throughout—raceways, rolling elements, and cage. This material is hardened and tempered to withstand the repetitive load cycles and impact from heavy material handling operations typical of manual pallet jack service.
Q: How is SKU 220050996 mounted into the wheel hub?
A: SKU 220050996 uses press-fit mounting, meaning the bearing is pressed directly into the wheel hub bore. The 20 mm inner diameter shaft or axle passes through the bearing, and the 47 mm outer diameter sits in the hub bore. This press-fit design requires proper equipment and alignment during mounting.
Q: What is the expected service life of SKU 220050996 in typical warehouse use?
A: Under normal manual pallet jack service with proper maintenance, SKU 220050996 typically operates for 3 to 5 years before replacement. Service life depends on load cycles, floor conditions, and environmental factors. If wheels begin to bind, feel rough, or develop noise, the bearing is likely worn and should be replaced.
