Fig. 2607.
A sectional view of a pillow block having this adjustable feature is shown in [Fig. 2606]. To provide increased seating bearing, and also means of side adjustment to pillow blocks, they are sometimes bolted to base plates as in [Fig. 2607], room being left in the bolt holes to permit of their being moved and adjusted upon the plate. The adjustment may be made by means of wedges, as at a, b in [Fig. 2607]. These base plates are usually employed when the pillow block is to be held against a wall.
Fig. 2608.
An inverted pillow block of similar construction, but designed for the head line (as the length receiving power from the engine or motor is termed) of the shafting, is shown in [Fig. 2608], but an improved form of the same has plungers so as to effect a vertical adjustment of the bearings.
