Application

This bearing is ideal for use in heavy industrial machinery such as mining equipment, conveyors, gearboxes, wind turbines, and pulp and paper processing machinery where high radial and moderate axial loads are present.

CO2 Impact

Opting for a repurposed bearing like this one prevents the emission of approximately 18.6 kg of CO2 compared to manufacturing a new one. This saving is equivalent to driving a car for 93 kilometers.

Availability

This item is in stock and ready for immediate dispatch. The bearing is new old stock (NOS) in its original, sealed packaging, though the outer box shows signs of wear. Order now from PLC2Day for expert support and fast delivery.

FAQ

What is the significance of the 'KEJW33' suffix?
The 'K' indicates a tapered bore with a 1:12 taper, designed for mounting with an adapter or on a tapered shaft. 'EJ' denotes a two-piece, window-type, steel cage. 'W33' signifies a lubrication groove and three oil holes in the outer ring to facilitate efficient relubrication.

Can this bearing be used in a high-temperature environment?
Standard Timken bearings like the 22319KEJW33 are dimensionally stabilized for operating temperatures up to 200 deg C (392 deg F). However, for continuous operation above 120 deg C (250 deg F), consult the Timken engineering manual regarding lubricant selection and potential adjustments to load ratings.

What is the correct procedure for mounting a bearing with a tapered bore?
Mounting a tapered bore bearing requires driving it up the tapered seat of a shaft or adapter sleeve. The correct fit is achieved by measuring the reduction in radial internal clearance. It is crucial to use a feeler gauge and follow the manufacturer's specified clearance reduction values to avoid overtightening, which can lead to premature failure.
