Thomson 1-1/4" LINEAR BRG SUPPORT BLOCK THP SB-20
Shaft support blocks are used for end or intermittent support where loads are light and deflection between supports is not a problem. Unlike shaft support rails, blocks do not permit longitudinal passage of open-type Ball Bushing® bearings. Type SB shaft support blocks enable clamping of shafts and eliminate the need for bolts, to maintain shaft position. Shimming is suggested for high-precision applications to eliminate the effect of variations in surface of base or manufacturing tolerances between supports.

Browning® 1045517 VP Series Type 2 Variable Pitch Sheave, 1-1/8 in Finished Bore, 5.35 in OD, 1 Groove, 3.9 to 4.7 in (3L)/4.2 to 5.2 in (A/4L)/4.4 to 5.4 in (B/5L) Dia Pitch, 3/4 to 1-1/8 in W Face
The principle of a variable pitch sheave is that the threaded angular faced discs forming the V-shaped groove in which the belt rides are movable. VP sheaves consist of a male with a threaded barrel, and a female with a threaded bore. The male section with threaded barrel has flat surfaces at 180 deg increments that allow a flat surface for the setscrew to mate with. When the discs are moved toward each other, the belt rides higher in the groove and the pitch diameter of the sheave is larger which increases the driven speed. When the discs are moved away from each other, the belt rides lower and the pitch diameter is smaller decreasing the driven speed. The common term for this speed adjustment is called number of turns open from closed position.
United Abrasives-SAIT Saitlam F™ 73980 Close High Performance Coated Abrasive Flap Disc, 4-1/2 in Dia, 7/8 in Center Hole, 80 Grit, Medium Grade, Zirconia Alumina Abrasive, Type 29 Conical Disc
Sure-Grip® quick detachable bushings are easy to install and remove. Split-through flange and taper provide a true clamp on the shaft that is equivalent to a shrink fit. All sizes except JA and QT have a set screw over the key to help maintain the bushing's position on the shaft until the cap screws are securely tightened. Versatile Sure-Grip® bushings permit the mounting of the same mating part on shafts of different diameters and the mounting of different sheaves on the same shaft using the same bushing.
