Product catalog summary

Overview: The document provides technical specifications for the ZK Series Sleeve, detailing variations with pressed steel and cast iron covers. It covers pillow block units, thick pillow block units, and 4-bolt flange units.

Specifications: It outlines dimensions, tolerances, and load ratings for housing numbers and shaft diameters from 20 mm to 55 mm. Variations in tolerance for the distance from the mounting bottom to the center of the spherical bore and bolt hole diameter are specified.

Procedures: Instructions are provided for identifying part numbers, fitting codes, and applicable grease fittings. Guidance on converting part numbers for bearings with adapters and details on triple seal type products are included.

Standards and Norms: The document specifies standard bolt sizes and basic factors for load ratings, mentioning housings made from nodular graphite cast iron.

Recommendations: Users are advised to refer to dimensional tables for applicable bearings and adapters. The importance of selecting correct part numbers and fitting codes for specific applications is highlighted.

Key Data from Tables: Tables provide detailed measurements for each unit type, including shaft diameter, housing dimensions, and mass. Load ratings are given in kN, with variations in tolerance specified in millimeters.

Critical Information: Emphasis is placed on adhering to specified tolerances and selecting the appropriate unit type based on application requirements. The availability of different cover materials and the significance of using correct grease fittings are highlighted.
