Thomson 1/2"-ID LINEAR BALL BEARINGS THP A-81420
Precision Steel Ball Bushing® bearings offer great improvements in efficiency, productivity and accuracy over high-friction plain bearings flat-ways. The all-steel design makes the bearing product line perfect for replacing plain bearings in high temperature applications. Rigid construction makes them very durable compared to ball bushing bearings with polymer components. When installed in a standard Thomson® pillow block, the Precision Steel Ball Bushing® bearing can self-align up to 3 deg in all directions.

Powers™ TempTAP™ 115 Traditional Standard Lavatory Faucet, 1 Handles, 2 gpm Flow Rate
Series 105 and 115 TempTAP™ thermostatic faucets feature an advanced thermal actuator to provide the latest in thermal protection. The single-lever cartridge, with integral ceramic discs, provides both temperature and volume control. TempTAP™ automatically mixes hot and cold water to deliver pre-set water within a specific range. In the event of cold water failure, the thermal actuator virtually shuts off the flow of hot water. TempTAP™ is listed to ASSE 1070, IAPMO cUPC, and NSF 61 Section 9 Annex G.
Keeney 1901K Extension Tube, 1-1/4 in OD x 6 in L, Slip Joint Connection, Brass, Import
Chrome plated 22 ga 6 in long extension tube with slip joint connection. 1-1/4 in inlet. Includes all necessary nuts and washers.
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.
