BEFORE INSTALLATION:
1. Make sure the shaft, bushing barrel & bore, BROWNING
®
split taper
bushed product bore, keys and keyways are free of burrs, paint,
etc. For idler bushings, make sure the bushing barrel and BROWN-
ING
®
split taper bushed product bore are free of burrs, paint, etc.
CAUTION
!
To avoid damage, supporting structure
including shafts and bearings must be
designed to handle transmitted loads
and belt tension(s).

WARNING
!
Lubricant on bushing barrel, hub or
screws could lead to breakage.
A. External key, except G, H and Idler Bushings.
B. Bushing barrel and Product bore are tapered.
C. Bushing cap screws.
D. Bushing barrel is split (except idler bushings).
E. Removal holes are threaded, installation holes are not.
2. For proper operation, make sure the shaft size is within the size
limits shown in Table 1. Some applications may benefit from tighter
shaft tolerances.
3. For light weight Products, the Bushing may first be loosely installed
into the BROWNING
®
split taper bored product, hereafter referred
to as “Product”, and then the assembly slid onto the shaft (Illustra-
tion 1 A & B). For heavier Products, it is usually easier to either first
slide the Bushing onto the shaft and then slide the Product onto the
Bushing (Illustration 2A), or first position the Product over the shaft,
next slide the Bushing onto the shaft, and then pull the Product
onto the Bushing (Illustration 2B). The “light weight Products” method
is common, however if the Bushing barrel has collapsed, it must be
wedged open (described below), and the “heavy Product” proce-
dure may be easier.
Heavier Product may require a hoist or other means of holding the
Product in position until the Bushing is installed into the Product.
When mounting on a vertical shaft, make sure the Bushing and the
Product do not drop during installation.

4. It may be necessary to slightly wedge open the saw slot on some
Bushings in order to start the bore and position the bushing onto
the shaft. A narrow edged regular screw driver may be used.
CAUTION
!
Mounting a BROWNING
®
Split Taper Bushing
on a shaft smaller than the size limits shown
in able 1 may result in a faulty assembly. The
assembly may come off the shaft or undesir-
able assembly runout may result.
CAUTION
Excessive wedging forces in Bushing saw
slot may damage or break Bushing. AVOID.
