About Plain Bearings

Oil-Embedded Flanged Sleeve Bearings

Also known as Oilite® bearings.

High-Load Oil-Embedded Flanged Sleeve Bearings

Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds.

Ultra-Low-Friction Oil-Embedded
Flanged Sleeve Bearings

For applications with frequent starts and stops, the oil in these bearings contains particles of slippery PTFE that lubricate the bearing during startup.

Food Industry Oil-Embedded Flanged Sleeve Bearings

The oil in these bearings is suitable for incidental contact with food.

High-Load Ultra-Low-Friction
Oil-Embedded Flanged Sleeve Bearings

With oil for reduced friction and iron for added strength, these bearings handle frequent stops and starts in high-load applications.

High-Load Food Industry Oil-Embedded
Flanged Sleeve Bearings

Support heavy loads that are often found in bottling and filling lines in food plants—these bearings contain extra iron and FDA-compliant oil. They’re flanged, so they handle loads both parallel and perpendicular to the shaft.

Oil-Embedded Flanged Sleeve
Bearings with Certification

These bearings come with a traceable lot number and material test report. They are also known as Oilite® bearings.

Grommets

Grommet Assortments

Keep grommets of various sizes on hand to solve whatever problems arise.

Cut-to-Size Grommets

Cut the thin layer of rubber in the center of these grommets to create custom IDs to securely hold and protect wire, cable, and cords. Push these grommets into place. They turn rough-edged and uneven holes into smooth, insulated holes. Commonly used in metal panels, they also damp vibration. Also known as webbed grommets.

Expandable Grommets

The center hole has flaps that flex to hold and protect various sizes of wire, cable, and cords while keeping out dust and debris. Push these grommets into place. They turn rough-edged and uneven holes into smooth, insulated holes.

High-Temperature Grommets

These flexible grommets withstand temperatures of 450° F or greater, which is approximately twice as high as our standard grommets. Push them into place to protect wire, cable, and cords by turning rough-edged and uneven holes into smooth, insulated holes. Commonly used in metal panels, they also damp vibration.

Push these flexible grommets into place to protect wire, cable, and cords by turning rough-edged and uneven holes into smooth, insulated holes. Commonly used in metal panels, they also damp vibration.

Locking Grommets

These grommets snap into place and have wings that expand against the sides of the hole to lock them in position. Use them to protect wire, cable, and cords by turning rough-edged and uneven holes into smooth holes.

Expandable Locking Grommets

The center hole has flaps that flex to hold and protect various sizes of wire, cable, and cords while keeping out dust and debris. Snap these grommets into place and their wings expand against the sides of the hole to lock them in position. Use them to turn rough-edged and uneven holes into smooth holes.

Split Grommets

A slit in the side of these grommets allows you to install them around wire, cable, and cords that are already in place. They snap into the hole and their wings hold them tight. Use them to turn rough-edged and uneven holes into smooth, insulated holes.

Pipe and Tubing Grommets

Snap-In Pipe and Tubing Grommets

These grommets have two flanges that snap around holes and flex to compensate for misalignment and movement of pipe and tubing. They're often used for routing applications in panel walls.

Push-In Pipe and Tubing Grommets

Press these flexible grommets into holes and their tapered inner wall will expand when pipe or tubing is inserted to hold them snugly in place. They're often used for routing applications on metal, plastic, and fiberglass tanks.

Fabric Grommets

Snap-In Fabric Grommets

No setting tools needed—snap the two parts together in a hole you've already cut to strengthen the hole and eliminate fraying. Use these grommets in tarps, covers, curtains, and other material.

Rolled-Rim Reinforcing Fabric Grommets

A rolled rim provides added grip while the elongated neck and teeth on the washer, also known as a spur washer, add reinforcement and reduce rotation so you can use these grommets in thick materials such as canvas. Press the grommets into a hole you've already cut. They strengthen and prevent holes from fraying in tarps, covers, and curtains. They also provide a way to run rope and cable through your material.

Self-Piercing Fabric Grommets

The sharp neck on these grommets cuts the material as you press them into place, eliminating the need for a cutting punch. They strengthen and prevent holes from fraying in tarps, covers, and curtains. They also provide a way to run rope and cable through your material.

Create a sanitary seal on through-wall piping, tubing, and cables in food-, cosmetic-, and pharmaceutical-processing areas.

Shrink-to-Fit Sealing Grommets

Apply heat and these grommets shrink around wire, cable, and cords to keep out dust, debris, and moisture.

Wet-Location Snap-In Sealing Grommets

Snap these grommets into place to hold wire, cable, and cords in wet locations and form a seal against dust, debris, and water.

Shaft Grommets

Support shafts, bearings, and other moving parts that are routed through a hole. These grommets are slippery to allow parts to move freely in the hole. Install them on thin sheet-metal panels.

Furniture Grommets

Eliminate clutter on desktops, countertops, benchtops, and other work surfaces by organizing wire, cable, and cords.

Brush-Style Furniture Grommets

Wire, cable, and cords pass through the grommet opening while the bristles fill in the gaps to control dust and debris. Use these grommets to eliminate cord clutter on desktops, countertops, benchtops, and other work surfaces.

Expandable Furniture Grommets

The center hole has flaps that flex to accommodate various sizes of wire, cable, and cords while still providing dust and debris protection. Use these grommets to eliminate cord clutter on desktops, countertops, benchtops, and other work surfaces.

Flexible Furniture Grommets

Squeeze these flexible grommets to open the center flap—once wire, cable, and cords pass through, the flap closes tightly for dust and debris protection as well as a finished look. Use them to eliminate cord clutter on desktops, countertops, benchtops, and other work surfaces.
