Adjustable Motor Bases

Sliding and Tilting Bases
    It is necessary to change the distance between the motor and driven shaft in order to change speed with an adjustable center drive. The best way to do this is with an adjustable motor base. Lovejoy offers four basic types of motor bases to satisfy requirements of space, convenience, interchangeability, motor frame size, and economy.
Sliding Cast Iron Type
    Models: 135, 145-60, 301, 302-3, 403, 305-8 and 310-30
    The original Lovejoy design, made of durable cast iron and steel.
    For remote control in hazardous or inconvenient locations, Lovejoy offers electric servo motor-controlled bases in some models of the cast iron bases, both direct coupled (ERC) and chain-driven (MRC). Also, stainless steel guide rods and adjusting screws are available on some models for severe environments or applications subject to wash down.
