Tritan UCPK207-23 Pillow Block Bearing Cast Iron Blue

Tritan UCPK207-23 Pillow Block Bearing

The Tritan UCPK207-23 is a new pillow block bearing with a cast iron housing and blue finish. It suits maintenance crews and original equipment builders who need a fixed, bolt-through mounted unit for 1 7/16 in cylindrical shafts. The radial ball insert uses alloy steel and is double sealed for contamination resistance. Grease lubrication supports a wide operating range from -40 Degrees F to 250 Degrees F.

Double sealed radial ball insert

The double sealed closure keeps grit and moisture out of the alloy steel rolling elements. Factory grease fill removes the need for initial lubrication during installation. Fixed expansion type means the bearing does not accommodate axial shaft growth, so alignment must be controlled by the surrounding structure. Bolt-through mounting uses a 5 in by 5 in hole pattern for secure attachment.

Cast iron housing with bolt-through base

Cast iron provides rigidity and vibration damping but adds mass compared to pressed steel alternatives. The base height of .708 in and width of 1.889 in set the centre height at 1 51/64 in above the mounting surface. Buyers who need a lighter housing or a different bolt pattern cannot use this unit. The fixed expansion design also rules out applications where the shaft must float axially.
