JL 69349 A/310 Bore 38 Mm, Metric Single Row Tapered Roller Bearings
The JL 69349 A/310 Metric single-row tapered roller bearings are widely used in various metric-sized mechanical equipment, such as automotive wheel hubs, gearboxes, differentials, industrial gearboxes, machine tool spindles, and agricultural machinery.
The JL 69349 A/310 bearing is a Metric single row tapered roller bearings with an inner diameter of 38 mm , an outer diameter of 63 mm, a width of 17 mm. GCr15SiMn rings, GCr15SiMn rolling mlement. Its dynamic radial rated load is approximately 45430 N, its static radial rated load is approximately 51846 N. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
JL 69349 A/310 bearings ( 38 mm x 63 mm x 17 mm) have the advantages of Simultaneously withstands combined loads (radial and axial loads) and is detachable for installation, and are therefore widely used in the Industrial gearboxes, automotive transmissions, machine tool spindles, agricultural machinery and conveying systems.

The JL 69349 A/310 Metric single-row tapered roller bearings mainly consist of an outer ring (with tapered raceways), an inner ring assembly (combined with a row of tapered rollers and a cage), tapered rollers, and a cage. The inner and outer rings are separable, and the contact angle varies depending on the design; dimensions conform to metric standards.
The separable design of metric single-row tapered roller bearings facilitates installation and disassembly, allowing for independent assembly of the inner and outer rings. They can simultaneously withstand radial loads and unidirectional axial loads, exhibiting high load-carrying capacity; a larger contact angle results in higher axial load capacity. They possess good rigidity and are suitable for medium- and high-speed applications.
