Frequently Asked Questions
Q: What bearing material is used in the LR0105?
A: The LR0105 features a sealed deep groove ball bearing constructed from GCr15 chrome steel, equivalent to SAE 52100 high carbon chromium steel. This premium bearing steel delivers precision, durability, and excellent resistance to fatigue under heavy cyclic loads common in industrial applications.
Q: What are the physical dimensions of the LR0105?
A: The LR0105 polyurethane wheel has an
Q: Why is the bearing sealed?
A: A sealed deep groove ball bearing protects the rolling elements and raceways from contamination, moisture, and dust. The seal extends bearing life, reduces maintenance frequency, and ensures consistent smooth motion in warehouse and manufacturing environments.
Q: What are the advantages of the polyurethane tire?
A: The abrasion-resistant polyurethane tire offers high impact resistance, excellent wear durability, and quiet operation. Polyurethane maintains good grip on concrete and tile floors, resists floor damage, and performs well in both dry and lightly wet conditions.
Q: Does the LR0105 have cross-reference part numbers?
A: No cross-reference part numbers are available for the LR0105. This is a unique assembly specification. When ordering replacement wheels, use the exact part number 0000-LR0105 to ensure correct fitment and bearing specifications.
Q: How does sealed bearing design extend service life?
A: The sealed design prevents dirt ingress and contamination of the bearing races and balls. GCr15 chrome steel combined with sealed protection maintains lubrication integrity and rolling smoothness, reducing wear and extending lifespan compared to open bearing designs.
Q: What equipment types use the LR0105?
A: The LR0105 is a universal bearing and wheel assembly used across various material handling and industrial equipment including pallet jacks, lift trucks, conveyor systems, and warehouse automation equipment from multiple manufacturers.
