UP Series Pulleys

SAVA’s inexpensive UP series pulleys are used for moderate load and speed application not requiring the use of more precise ground bearings. The bulk of all applications falls into this category. The UP series pulleys are furnished with an open-type precision machined ball bearing, which is lightly lubricated.
UP2044, UP2050, and UP2063 are also available with open-type, ABEC1 precision ground bearings with ball retainers and are very free turning. If you wish to purchase a precision ground bearing for these pulleys, specify the pulley part followed by R2X1 Bearing; e.g., UP2044R2X1.

MP Series Pulleys

This line of nylon pulleys offers a bushing of porous, sintered, self-lubricating bronze. The bushings are oil-impregnated at the factory. This vacuum impregnated oil, equivalent to SAE 30, supplements the pure bronze structure and forms a hydraulic cushion which absorbs unusual shocks and permits the bushing to carry heavier loads than SP or UP series pulleys. They are highly corrosion and wear resistant.

Storage

SAVA’s nylon pulleys with oil-impregnated sintered bronze bushings can be stored indefinitely in suitable containers using plastic bags, wax paper, metal, glass, etc. Woods, ordinary paper and cardboard are not suitable since they absorb oil from the bushings. Properly stored SAVA’s oil-impregnated bushings retain their oil supply indefinitely.
