ZWA split roller bearings in rod end housings provide a simple way of mounting roller bearings on cranks. As the complete bearing and housing unit is split radially, cranks can be made solid rather than being built-up or overhung. Typical applications include shaker screens and classifiers.

Rod ends are available to suit 100, 01/01 E and 02 Series bearings as shown on pages 518 to 524 and 538 to 546.

Each rod end consists of a split outer casing, which encloses a fixed (gr) bearing in a swivel cartridge (refer to page 515). Two basic configurations are available - the T type and the`shoe` type. These can be modified to suit various rods and attachments.

Standard rod ends are of grey iron. Spheroidal graphite iron or steel versions are available.

Rod ends are supplied with matched cartridge to reduce the clearance between the cartridge and rod-end (S1 fit).

Except for very slow speed applications, bearings with C2 clearance should be specified.

Dimensions and load capacities of housings should be confirmed before finalising designs.

Shaft Dimensions

Journals should be machined to h6 tolerance. Close tolerance machining to the sides of the journal is not required. These are clearance only (i.e. not locating) as the bearing is positioned by the inner race being clamped onto the shaft.

The journal widths and fillet radii listed in the tables are suggested dimensions to clear standard ZWA cartridges. Special cartridges may be supplied if narrower journals are required.
