TIMKEN 6004-2RS Double Rubber Seal Bearings 20x42x12mm 2 Pack

Description

Product Overview

The TIMKEN 6004-2RS double rubber‑seal bearing combines precision engineering with robust materials to meet demanding industrial applications. Each bearing features a deep‑groove ball design that accommodates radial loads efficiently while maintaining low friction. The outer and inner rings are forged from high‑grade steel, providing excellent hardness and wear resistance. Two rubber seals (2RS) protect the internal balls from contaminants and retain lubrication, extending service life even in dusty or moist environments. With dimensions of 20 mm inner diameter, 42 mm outer diameter, and 12 mm width, the bearing fits standard shafts and housings, simplifying retrofits and new installations. Pre‑lubricated with a high‑temperature grease, the unit is ready for immediate use, reducing downtime and maintenance costs. Key performance figures include a dynamic load rating of 9.4 kN, a static load rating of 5 kN, and a grease reference speed of 17,000 rpm, ensuring reliable operation across a broad speed range.

Usage

These bearings are engineered for a variety of power‑transmission scenarios, making them a versatile choice for manufacturers and maintenance professionals. Typical applications include electric motor shafts, gearboxes, conveyor rollers, and industrial pumps where consistent rotational stability is critical. The sealed design allows operation in harsh conditions such as chemical processing plants, food‑grade facilities, and outdoor equipment exposed to rain or dust. Because the bearing is pre‑lubricated, it can be installed directly into the assembly without additional greasing steps, which is especially valuable in high‑volume production lines where time savings translate to cost efficiency. The compact 12 mm width enables use in space‑constrained designs, while the 20 mm bore accommodates a wide range of standard shafts.

FAQ

What does the 2RS designation mean?

2RS indicates that the bearing has two rubber seals—one on each side of the bearing—to keep lubrication in and contaminants out, providing enhanced protection for sealed applications.

Can these bearings be used in high‑speed applications?

Yes. The bearing is rated for a grease reference speed of 17,000 rpm and an oil reference speed of 25,000 rpm, making it suitable for many high‑speed motor and spindle applications when properly lubricated.

Is the pre‑lubricated grease suitable for all operating temperatures?

The supplied grease performs well up to approximately 120 °C. For temperatures beyond this range, a specialized high‑temperature grease may be recommended, and TIMKEN can advise on the best option.

How do I verify the correct fit for my equipment?

Check the shaft bore (20 mm), outer diameter (42 mm), and width (12 mm) against your equipment specifications. The bearing’s dimensions conform to standard ISO 15‑720 series sizes, ensuring compatibility with most industrial designs.

What warranty does TIMKEN provide for this bearing?

TIMKEN offers a limited warranty covering manufacturing defects for a period of one year from the date of purchase, subject to proper installation and usage according to the product guidelines.
