3806/711.2-2LS/YA4/P5 914.4 mm 711.2 mm 390 mm Frequently Asked Questions about 3806/711.2-2LS/YA4/P5 Four-Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for 3806/711.2-2LS/YA4/P5 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 3806/711.2-2LS/YA4/P5. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Sourcing 3806/711.2-2LS/YA4/P5 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Four-Row Tapered Roller Bearings.
Each 3806/711.2-2LS/YA4/P5 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 (711.2 mm bore side) ensures perfect planar contact without edge binding.
