Industrial Flange Bearing

This Timken SCJT unit is a 1-inch bore, two-bolt flange bearing with a cast-iron rhombus housing and a radial ball insert made of alloy steel. It comes double-sealed and pre-lubricated with NLGI #2 equivalent grease, ready for fixed mounting on conveyors, fans or light machinery. The GYA100RRB insert is included.

Speed and Temperature Headroom

The bearing is rated for a maximum speed of 5,520 RPM and an operating range from -65 to 200 degrees F, giving wide headroom for typical line-shaft and blower duties. At the top of the speed range or in sustained high-heat environments the fixed-expansion design offers no axial float, so thermal growth must be managed by the shaft layout.

Mounting and Seal Constraints

Two bolt holes on 11/64-inch centres and an overall length of 4 55/64 inches fix the mounting footprint, while the 2 3/4-inch overall height sets the shaft centreline. The double seals retain grease and exclude dust but are not rated for high-pressure washdown or immersion, limiting use in wet-process zones.

Highlights

  • Radial ball design for smooth rotation
  • Double sealed closure keeps contaminants out
  • Cast iron rhombus housing provides rigid mounting
  • Fixed expansion type maintains shaft alignment
  • Operates from -65 to 200 degrees F

Questions about this item

Will the 1 in bore fit the shaft on my existing conveyor roller?

The bearing has a 1 in cylindrical bore with a fixed expansion type, so it will slide onto any shaft of that exact diameter.

How can I confirm the GYA100RRB insert is running correctly after mounting?

Listen for smooth rotation without grinding and check that the housing temperature stays below 200 Degrees F during operation.

Does the box include mounting bolts for the 2-hole rhombus flange?

The package contains the bearing unit with the GYA100RRB insert already installed; mounting bolts are not included and must be sourced separately.
