"N" 2 HOLES - 180 APART L H J SET SCREW 1 ST FLANGETTE UNIT Pressed steel housed units designed for light-duty applications. Available in shaft sizes from 6.35 mm - 12.7 mm ( 1 /4 to 1 /2 inch). Designed to simplify mounting on side plate or frame-type housings. Two identical steel stampings house a clamp-type bearing with a spherical O.D. outer ring. Spherical inside surface of each stamping mates with the spherical O.D. of the bearing, providing initial self-alignment at mounting. Offers features of basic clamp-type bearing. Available with sealed or shielded construction. Radial load capacity is 25 percent of basic bearing's dynamic load rating at 33.3 RPM. Inspected to ABEC-1 tolerances, except bore. Suggested shaft tolerance: Nominal bore size to -.0005 in. resulting in .000 in. to .001 in. loose-shaft fit. RTF-RUBBER TIRE FLANGE HOUSED UNIT Synthetic, conductive elastomer of Durometer hardness 80-85 facilitates mounting of standard cylindrical O.D. bearings in side plate of frame-type housings. Generous taper on entrance corner of rubber cartridge simplifies insertion of unit into side panel, assuring reasonable squareness of bearings when fully mounted. Bearing is positioned by integral flange of the rubber cartridge. Resiliency of elastomer accommodates wider than the standard suggested housing bore tolerance. Greater flexibility in adjusting to minor shaft and/or housing alignment. Helps reduce airborne noise and structural vibration. Additional advantages are similar to features of basic clamp-type bearing design. Due to deflection characteristics of the elastomer, radial and thrust ratings for the RTF Series are 10 percent of the basic bearing's dynamic load rating at 33.3 RPM. Unit Bore** Set- Max.
