134.50.3150.11K 1985 mm 2868 mm 2445 mm 3432 mm 270 mm Frequently Asked Questions about 134.50.3150.11K Three-row Cylindrical Roller Slewing Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing 134.50.3150.11K is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
To ensure optimum performance of CHG Bearing 134.50.3150.11K Three-row Cylindrical Roller Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 2868 mm bore. For the 3432 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Yes, 100% of 134.50.3150.11K Three-row Cylindrical Roller Slewing Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
For international ocean and air freight, CHG Bearing packs 134.50.3150.11K with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
