Snapidle - Pillow Blocks

We stock bore sizes from 1/2 inch to 3 inch.

Our Self-Aligning Inserts are designed to replace a self-aligning ball bearing or roller bearing having a spherical O.D. in the conventional housing. They are self-aligning to the same degree as a steel bearing, therefore no changes are necessary in existing equipment when switching to plastic bearing inserts.

HIGH TEMPERATURE HIGH TEMPERATURE MATERIAL ™ BEARINGS

Most commercial plastic and metallic bearings have operating temperature ranges of approximately 200°F.In the 300°F to 500°F range exotic seals, greases, bearing fits, clearances and housings are required.It is possible to eliminate many of the associated purchasing, installation, and maintenance costs associated with these applications by utilizing Snapidle's HT series bearings, especially in the case of bearing inserts (PI-HT).Requiring no lubrication, retro-fitted in existing housings, and having operating temperature ranges to 600°F, these bearing products are the economical, simple answers to problem applications in the bakery, paving, and processing industries. Utilizing the same dimensional and engineering data of Snapidle's other bearing products, the HT series is available in a variety of bore ranges to fit many applications. Machined from pure, virgin high temperature material ™, these products are new technology solutions to age old industry problems.

SPEED AND LOAD DATA FOR PLASTIC PILLOW BLOCKS (UHMW)

This data applies to UHMW Pillow Block Bearings in unlubricated conditions. Since the upper operating temperature limits of UHMW bearings are 180° - 200°F, and since this material has a low coefficient of thermal conductivity, PV values must be carefully calculated.

The information in the table below has been calculated so as not to exceed the following limits for UHMW in a bearing application:

• Maximum Pressure (P) = 800 lbs/in²
• Maximum Velocity (V) = 50 surface feet/minute

Note: For UHMW the combination of PV may not exceed 3000. For PV's exceeding 3000, consult us for material recommendations.

If ambient temperatures are low or if the bearing is operating in water or other liquids and is sufficiently cooled, the PV limits may be increased as long as bearing temperature limits are not exceeded. The use of lubrication canpotentially increase the operating PV limits by providing a lower coefficient of friction on the bearing.
