Demanding applications call for reliable solutions. Improve your equipment's performance and reduce your downtime and maintenance costs by turning to Timken tapered roller bearings.
When you purchase a Timken bearing, you're investing in a product that's designed with you in mind.
Reliability. Expert craftsmanship, well-equipped production facilities and an ongoing investment in technology ensure our products are synonymous with quality and reliability. Our tapered roller bearings stand up to extreme situations, including high-corrosive, high-temperature, vacuum or low-lubrication environments.
Versatility. Use Timken tapered roller bearings to help your equipment excel when it faces combined radial and thrust loads.
Our bearings are uniquely designed to manage both types of loads on rotating shafts and in housings.
Choice.
 From single- to double- to four-row configurations to thrust, choose from nearly 26,000 product combinations to find the right bearing for your application.
Each tapered roller bearing contains four interdependent components: the cone (inner ring), the cup (outer ring), tapered rollers (rolling elements) and the cage (roller retainer). Tapered angles allow our bearings to efficiently control a combination of radial and thrust loads. The steeper the outer ring angle, the greater ability the bearing has to handle thrust loads. To provide a true rolling motion of the rollers on the raceways, the extensions of the raceways and the tapered surfaces of the rollers come together at a common point, the
apex, on the axis of rotation.
We designed this catalog to help you find the Timken bearings best suited to your equipment needs and specifications. The product tables list many of the bearing types that are specifically used in thrust positions. For other bearing types,
please refer to the respective Timken product catalog reference.
Timken offers an extensive range of bearings and accessories in both imperial and metric sizes. For your convenience, size ranges are indicated in millimeters and inches. Contact your Timken engineer to learn more about our complete line for the special needs of your application.
This publication contains dimensions, tolerances and load ratings, as well as engineering sections describing mounting and fitting practices for shafts and housings, internal clearances, materials and other bearing features. It provides valuable assistance in the initial consideration of the type and characteristics of the bearings that may best suit your particular needs.
ISO and ANSI/ABMA, as used in this publication, refer to the International Organization for Standardization and the American National Standards Institute/American Bearing

Timken suggests the following storage guidelines for our finished products (bearings, components and assemblies, referred to as “products”):
• Unless directed otherwise by Timken, products should be kept in their original packaging until they are ready to be placed into service.
• Do not remove or alter any labels or stencil markings on the packaging.
Products should be stored in such a way that the packaging is not pierced, crushed or otherwise damaged.
• After a product is removed from its packaging, it should be placed into service as soon as possible.
• When removing a product that is not individually packaged from a bulk pack container, the container should be resealed immediately after the product is removed.
• The storage area temperature should be maintained between 0° C (32° F) and 40° C (104° F); temperature fluctuations should be minimized.
• The relative humidity should be maintained below 60 percent and the surfaces should be dry.
• The storage area should be kept free from airborne contaminants such as, but not limited to, dust, dirt, harmful vapors, etc.
• The storage area should be isolated from undue vibration.
• Extreme conditions of any kind should be avoided.
Due to the fact that Timken is not familiar with your particular storage conditions, we strongly suggest following these guidelines. However, you may be required by circumstances or applicable government requirements to adhere to stricter storage requirements.
Most bearing components typically ship protected with a corrosion-preventive compound that is not a lubricant. These components may be used in oil-lub
