TIMKEN

TIMKEN, founded in 1899 in St. Louis, Missouri, USA, is a manufacturer of bearings and mechanical power transmission components. The company's product line includes radial ball bearings, spherical insert bearings, pillow block bearings, flange-mount bearings, and cartridge bearing units. These products serve applications in industrial machinery, material handling, agricultural equipment, and conveyor systems. TIMKEN bearings are available in both inch and metric systems, with bore sizes ranging from 5/8 in to 95 mm and outer diameters up to 200 mm. Housing materials include cast iron, and locking mechanisms include set screws and eccentric collars. Sealing options include double seals and open designs. Lubrication typically uses NLGI #2 grease. 3G Electric supplies over 560 SKUs of TIMKEN bearings, including general purpose spherical insert bearings (e.g., RA115RRB with 1 15/16 in bore), rubber-mounted insert bearings (e.g., RCSM1 with 1 in bore), high-capacity radial ball bearings (e.g., 6319 with 95 mm bore), and medium duty pillow block bearings (e.g., YASM 1-7/16 with 1 7/16 in bore). Flange-mount options include 4-bolt and square configurations, such as the SCJ 5/8 with 5/8 in bore and the YCJ 30 SGT with 30 mm bore. These products are designed for radial loads and moderate speeds, with maximum speeds up to 4700 RPM for grease-lubricated units. The bearings are suitable for environments requiring corrosion resistance and reduced maintenance, with double-sealed closures to retain lubricant and exclude contaminants. 3G Electric supports the TIMKEN line by offering a broad inventory of standard and specialty bearings, enabling procurement specialists to source replacements for existing equipment or new installations. The catalog includes detailed specifications such as bore type, outer ring width, mounting bolt size, and industry numbers, allowing engineers to match parts to application requirements without ambiguity.

Frequently asked questions

Common questions about TIMKEN from 3G Electric.

What types of TIMKEN bearings does 3G Electric stock?

3G Electric stocks over 560 SKUs of TIMKEN bearings, including general purpose spherical insert bearings, rubber-mounted insert bearings, high-capacity radial ball bearings, medium duty pillow block ball bearings, and flange-mount ball bearings. Examples include the RA115RRB spherical insert bearing with a 1 15/16 in bore, the RCSM1 cartridge bearing unit with a 1 in bore, and the 6319 radial ball bearing with a 95 mm bore. These are available in both inch and metric systems.

What locking mechanisms are available on TIMKEN pillow block bearings from 3G Electric?

TIMKEN pillow block bearings supplied by 3G Electric feature either set screw or eccentric collar locking mechanisms. For example, the YASM 1-7/16 pillow block bearing uses set screws, while the RAS 1 pillow block bearing uses an eccentric collar. Both are housed in cast iron and are designed for medium duty applications.

Are TIMKEN flange-mount bearings available in metric sizes?

Yes, 3G Electric offers TIMKEN flange-mount bearings in metric sizes. For instance, the YCJ 30 SGT is a square flange mount bearing with a 30 mm bore, cast iron housing, and set screw locking. It uses NLGI 2 lithium complex grease and has a mounting bolt size of 3/8 in.

What is the maximum speed rating for TIMKEN pillow block bearings from 3G Electric?

The maximum speed rating for TIMKEN pillow block bearings varies by model. For example, the YASM 1-7/16 pillow block bearing has a maximum speed of 4700 RPM when lubricated with grease. This rating is specific to the bearing's design and lubrication, and should be verified against application conditions.

What sealing options are available on TIMKEN spherical insert bearings?

TIMKEN spherical insert bearings from 3G Electric are typically double sealed. For example, the RA115RRB and GY1015KRRB SGT both feature double seals to retain lubricant and exclude contaminants. This design reduces maintenance requirements in dusty or wet environments.

Can I find TIMKEN bearings with open designs for high-speed applications?

Yes, 3G Electric stocks TIMKEN radial ball bearings with open designs, such as the 6319 bearing (MPN 319W). This bearing has a 95 mm bore, 200 mm OD, and 45 mm width, and is open (no seals or shields), making it suitable for applications requiring higher speeds or custom lubrication systems.
