SMITH BEARING

SMITH BEARING is a manufacturer of cam followers and track rollers, supplying components used in linear motion, conveyor systems, and material handling equipment. The product line includes stud-type and yoke-type cam followers, track rollers, and eccentric yoke shafts, available in both inch and metric dimensions. Standard-duty and heavy-duty variants are offered, with stud materials including bearing steel and stainless steel. Seal configurations include double-sealed and open designs, and profiles include crowned and flat options. Some models are designated as food-grade, using stainless steel construction suitable for washdown environments. SMITH BEARING components are specified by roller diameter, thread size, overall length, and head dimensions, with load ratings and speed limits defined in manufacturer datasheets. 3G Electric stocks over 560 SKUs from SMITH BEARING, covering general-purpose stud cam followers (e.g., MCR-32-SB, MCR-90-SB), heavy stud cam followers (e.g., HR-2-B, HR-2-1/4-XB-SS-FG), non-metallic stud cam followers (e.g., BCR-7/8-X), self-lubricated yoke cam followers (e.g., BYR-1-1/8-X), and eccentric yoke shafts (e.g., SHAFT-1-1/4-E). Each SKU is supported by a datasheet with specifications such as duty type, system of measurement, stud material, thread size, row count, seal type, and drive type (hex socket or screwdriver slot). The range includes metric sizes from 32 mm to 90 mm roller diameter and inch sizes from 7/8 in to 2 1/4 in roller diameter. Applications include cam actuation, track guidance, and roller support in packaging machinery, automated assembly lines, and industrial processing equipment. 3G Electric provides logistics support for global shipment, enabling procurement specialists and maintenance managers to source SMITH BEARING components with documented specifications for replacement or new installations.

Frequently asked questions

Common questions about SMITH BEARING from 3G Electric.

What is the difference between SMITH BEARING stud cam followers and yoke cam followers?

Stud cam followers have an integral threaded stud for mounting directly into a tapped hole or bracket, while yoke cam followers have a smooth bore and are mounted on a separate shaft or pin using a yoke. SMITH BEARING offers both types: stud cam followers (e.g., MCR series) and yoke cam followers (e.g., BYR series). The choice depends on the mounting configuration and load requirements of the application.

Are SMITH BEARING cam followers available in stainless steel for food-grade applications?

Yes, SMITH BEARING offers food-grade heavy stud cam followers in stainless steel, such as the HR-2-1/4-XB-SS-FG model. These are designed for washdown environments and resist corrosion from cleaning agents. They feature double-sealed construction to prevent ingress of contaminants.

What seal options are available for SMITH BEARING track rollers?

SMITH BEARING track rollers and cam followers are available with double-sealed or open configurations. Double-sealed units (e.g., MCR-32-SB) have seals on both sides to retain lubrication and exclude debris, suitable for dirty or wet environments. Open units (e.g., HR-2-B) allow for re-lubrication and are used in clean, high-speed applications.

How do I select the correct SMITH BEARING cam follower for a heavy-duty application?

For heavy-duty applications, select a cam follower from the heavy-duty series, such as the HR-2-B (2 in diameter) or HR-2-1/4-XB-SS-FG. These have thicker outer rings and higher load ratings than standard-duty models. Verify the roller diameter, stud thread size, and overall length match your mounting dimensions. Consult the datasheet for dynamic and static load capacities.

Does SMITH BEARING offer non-metallic cam followers for low-noise or non-marring applications?

Yes, SMITH BEARING produces non-metallic stud cam followers, such as the BCR-7/8-X, which uses a non-metallic roller material. These are suitable for applications where metal-to-metal contact must be avoided, such as on soft or finished surfaces, or where reduced noise is required. They are available in inch sizes.

What is the purpose of eccentric yoke shafts from SMITH BEARING?

Eccentric yoke shafts, like the SHAFT-1-1/4-E, allow for adjustment of the roller position relative to the mounting surface. By rotating the eccentric shaft, the center distance between the roller and the mounting hole changes, enabling fine-tuning of track alignment or cam timing without moving the entire assembly.
