33115 SKF 75x125x37 Tapered Roller Bearing

Overview

33115 SKF is a single-row tapered roller bearing with dimensions of 75x125x37 mm, engineered to accommodate combined radial and axial loads. Its tapered raceways and rollers direct load through a common pressure point, providing high stiffness and accurate shaft guidance. The separable cone and cup construction simplifies installation and adjustment in industrial bearing arrangements requiring controlled internal clearance or preload.

Industrial Applications

SKF 33115 is suitable for industrial gearboxes, transmissions, wheel hubs, heavy machinery, agricultural equipment, construction machinery and mechanical drive systems. A single-row tapered roller bearing accommodates axial load primarily in one direction and is frequently combined with a second bearing where axial location in both directions is required.

Construction

The bearing consists of a cone with inner ring, tapered rollers and steel sheet cage, plus a separate outer ring or cup. SKF lists the 33115 as a single-row, open tapered roller bearing. The geometry provides combined-load capability, while the separable design enables the cone and cup to be mounted independently.

Material

The rings and tapered rollers are manufactured from bearing steel for repeated rolling contact under high mechanical loads. Correct service life depends on lubricant selection, contamination control, operating temperature, shaft and housing fits, alignment and bearing adjustment. The open design requires lubrication supplied by the bearing arrangement.

FAQ

What type of bearing is SKF 33115?

It is a metric single-row tapered roller bearing designed to accommodate combined radial and axial loads.

What are the dimensions of SKF 33115?

The bearing has a 75 mm bore diameter, 125 mm outside diameter and 37 mm total width.

What are the load ratings of 33115 SKF?

SKF specifies a basic dynamic load rating of 216 kN and a basic static load rating of 265 kN.

Can SKF 33115 locate a shaft axially in both directions?

A single-row tapered roller bearing accommodates axial load primarily in one direction. Opposed bearing arrangements are commonly used when axial location in both directions is required.

What should be verified when replacing a 33115 bearing?

Confirm the 33115 designation, 75x125x37 mm dimensions, bearing arrangement, required clearance or preload, load conditions, lubrication and operating speed.
