Sealed Deep Groove Ball Bearing Assembly

Frequently Asked Questions

Q: What are the exact dimensions of the BRG1107-1 bearing?
A: The BRG1107-1 has a 20 mm bore (±0.01 mm), 47 mm outer diameter (±0.01 mm), and 14 mm width (±0.01 mm). These precision tolerances ensure accurate fitment on manual pallet jack load and steer wheel assemblies.

Q: Which equipment brands and models does the BRG1107-1 bearing fit?
A: The BRG1107-1 is compatible with manual pallet jack load wheel and steer wheel applications across Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT material handling equipment. Verify dimensions match your specific equipment model.

Q: What material is the BRG1107-1 constructed from?
A: The BRG1107-1 features a high carbon steel raceway with a polyamide reinforced cage and dual contact rubber seals. This configuration provides durability under standard pallet jack loading while protecting against moisture and contaminants.

Q: What is the seal design of the BRG1107-1 and how does it protect the bearing?
A: The BRG1107-1 uses dual contact rubber seals that protect the bearing from water, dust, and debris typical in warehouse and storage environments. The seals maintain grease retention and extend bearing life compared to open bearing designs.

Q: Is the BRG1107-1 pre-lubricated and what is its expected service life?
A: The BRG1107-1 comes factory pre-lubricated. Service life depends on load cycles, usage frequency, and environmental conditions. Monitor for noise, grinding, or resistance to identify worn bearings. The sealed design extends life in standard warehouse duty.

Q: How does the polyamide cage in the BRG1107-1 compare to other cage materials?
A: The polyamide reinforced cage in the BRG1107-1 provides low friction operation and resistance to moisture and corrosion. This material selection ensures reliable performance across standard and cold storage warehouse conditions.
