BA240-3 Chrome Steel Walking Excavator Bearings are double row deep groove ball bearings designed for high to very high speed applications where single row deep groove ball bearings lack sufficient load carrying capacity.

• Double row design provides significantly higher load capacity than single row bearings
• Optimized for high to very high speed operations
• Available with various cage materials including sheet steel, brass, and polymer
• Sealed versions ensure optimal lubrication in working conditions
• Wider design than single row bearings of same bore and outside diameter

Standard BA240-3 bearings feature sheet steel cages. Polymer cages are available for specific applications requiring enhanced friction and lubrication capabilities.

Primarily produced in sealed versions to maintain optimal lubrication under working conditions. Features CRAFT bearings grease with lithium 12-hydroxy stearic thickener and refined mineral oil with rust and oxidation inhibitors. Operating temperature range: -20°C to +120°C.

• Single row angular contact ball bearings
• Double row angular contact ball bearings
• Four-point contact ball bearings
• Super-precision angular contact ball bearings
• Double row cam rollers
• Hub bearing units

Our excavator bearing portfolio includes: walking bearings, slewing bearings, needle roller bearings, transmission bearings, walking motor bearings, driving bearings, joint bearings, slewing support bearings, and inch non-standard bearings specifically designed for excavator applications.

Proper installation and removal methods should consider bearing structure, size, and component compatibility. Pressure must be applied directly to the bearing ring tight end surface, never through rolling elements, to prevent surface indentation and damage. Avoid applying pressure to cages, seals, dust covers, and other easily deformed components.

We maintain over 4,000 square meters of three-dimensional warehouse space and 2,000 square meters of outdoor warehouse facilities, ensuring adequate inventory levels and rapid response to customer requirements. Fast delivery is our competitive advantage.
