BT2-8000 560 mm 360 mm Frequently Asked Questions about BT2-8000 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each BT2-8000 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (360 mm bore side) ensures perfect planar contact without edge binding.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for BT2-8000, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
In its sealed configuration (Open Type), CHG Bearing pre-charges BT2-8000 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing BT2-8000 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
