Simplicity Plain Linear Bearings | Self- Lubricating

The red anodized aluminum shell identifies the inch series, which is available in off-the-shelf industry standard sizes from 3/16” to 4” and is interchangeable with linear ball bearings and some bronze bushings. The closed type of linear plain heavy duty bearing is ideal for handling loads in all directions and offers several mounting options. The Frelon Gold lined bearings offer static loads up to 100,500 lbs and the Frelon J & W liners carry up to 50,250 lbs.

Closed Compensated Linear Bearings have a running clearance that performs like a standard ball bearing. The additional clearance is built into the inner diameter, but all other dimensions are the same as the standard linear bearings. The compensated running clearance makes it ideally suited for parallel shaft applications.

Offered in the same sizes and maximum static loads as the standard Closed Linear Plain Bearing. The self-aligning heavy duty linear bearing has a crown on the outer diameter allowing the bearing to re-align itself in binding situations. Specifically designed to easily retrofit straight bore housings, the bearing will allow 1/2° of misalignment capability from centerline (1° overall).

This Self-Aligning Compensated Linear Plain Bearing has additional clearance built into the inner diameter, but all other dimensions are the same as the precision bearings. Ideally suited for parallel shaft applications, the heavy duty bearing has a crown on the outer diameter allowing the bearing to re-align itself in binding situations. Specifically designed to easily retrofit straight bore housings, the bearing will allow 1/2° of misalignment capability from centerline (1° overall).

The open version of the standard inch closed linear bearing has an opening which is designed to allow use on fully supported shafting for greater system rigidity. This linear bearing offers all the same features and benefits as the closed linear bearing. The open style is available in sizes 1/4” ID to 4” ID and with static load capacities up to 100,500 lb (444 kN). 

The Open Compensated Linear Plain Bearing operates akin to a conventional linear ball bearing, exhibiting comparable performance characteristics. The heavy duty linear bearing notably incorporates supplementary clearance within the inner diameter while maintaining precision across all other dimensions. This design feature renders it optimally tailored for parallel shaft applications.

This plain linear bearing is adept at managing multidirectional loads and provides versatile mounting options. Featuring added clearance in the inner diameter while maintaining precision dimensions, it excels in parallel shaft applications. 

The blue shell distinguishes the ISO metric series, available in standard sizes and interchangeable with linear ball bearings and certain bronze bushings. Inner diameters range from 5 mm to 80 mm, with static load capacities up to 271.9 kN (61,000 lbs). Featuring a crowned outer diameter, the linear motion bearing facilitates self-alignment in binding situations and is designed for easy retrofitting into straight bore housings. Additionally, it offers 1/2° of misalignment capability from the centerline (1° overall), ensuring adaptable performance across different applications. 

The blue shell distinguishes the metric series, featuring off-the-shelf industry standard sizes and an alternative for linear ball bearings and select bronze bushings. This closed-type, self-aligning linear plain bearing is compensated for enhanced adaptability along uneven shafts. The crowned outer diameter enables self-realignment in binding scenarios and is tailored for straightforward retrofitting into straight bore housings.  

This is the open type of compensated linear plain bearing that is ideally suited for parallel shaft applications. Additional clearance is built into the inner diameter, but all other dimensions and ratings are the same as the standard bearings.

The opening in the metric Open Plain Linear Bearing is designed to allow for use on fully supported shafting for greater system rigidity. It offers all the same features and benefits as its closed counterpart. The open style is available in sizes 5 mm to 80 mm inner diameter with static load capacities up to 271.9 kN (61,000 lbs).

The Thin Wall Linear Plain Bearing has the same construction and smooth operation as our standard bearings, but in a more compact package. Designed to be interchangeable with compact linear ball bearings and bronze bushings, our Thin Wall Linear Bearings have inner diameters from 6 mm to 50 mm and static load capacities up to 92 kN (20,000 lbs).

The Compensated Thin Wall Linear Plain Bearing offers the same robust construction and seamless performance as our standard bearings but in a more space-efficient design. These bearings feature inner diameters ranging from 6 mm to 50 mm and static load capacities up to 92 kN (20,000 lbs) as well as additional clearance on their inner diameters.

Same construction and smooth operation as the FM series but in a more compact package. Designed to be interchangeable with compact ball bearings and bronze bushings.

The green anodized aluminum shell identifies the JIS metric series, which is available in off-the-shelf industry standard sizes and interchangeable with linear ball bearings and some bronze bushings. The closed linear plain bearing style is for use with end-supported shafting. Inner diameter sizes range from 6 mm to 150 mm with static load capacities up to 741 kN (166,000 lbs).

This is the closed, self-aligning style linear plain linear bearing that is used with end-supported shafting. This linear bearing has a crowned outer diameter allowing the linear bearing to re-align itself in binding situations. It was specifically designed to easily retrofit straight bore housings. 

The green shell identifies the JIS metric series that conforms to JIS tolerance standards. This is the closed, self-aligning and compensated style linear bearing that is used with end-supported shafting. The crowned outer diameter and additional running clearance contribute to a best in class, heavy duty linear bearing.

This is the closed and compensated linear motion plain linear bearing style which allows for greater shaft flexibility including use with end-supported shafting.
