Product Overview:
This document details specifications for HASCO linear ball bearings (Linearkugelbuchse) without a centering projection (flush location head). The bearings are made from material 1.7131 hardened to 60-62 HRC and 3.2315.

Material and Hardness:
- Material: 1.7131 hardened steel (60-62 HRC)
- Secondary material: 3.2315

Dimensional Specifications:
The document provides dimensional parameters with tolerances for various bearing sizes. Key dimensions include:
- d1, d3, d4, d5: diameters with specified tolerances (e.g., d1 k1 ±0.05)
- l1: length dimension
- a1, b1: additional dimensional parameters with tolerances (+0.15, +0.05)

Size Variants and Corresponding Dimensions:
Several size variants are listed with their respective dimensions (in mm):
- Example: For bearing Z1100/27 x 9, dimensions include k1=6, a1=18.3, b1=1.3, d5=19, d4=25, d3=20, l1=27, d1=9
- Other sizes range up to Z1100/100.15 x 116 with corresponding dimensional increments.

Part Numbering:
- Bearings are identified by the prefix Z1100 followed by size dimensions (e.g., Z1100/27 x 9).

Summary of Critical Parameters:
- Tight tolerances on diameters and lengths ensure precise fit.
- Material hardness ensures durability and wear resistance.
- Absence of centering projection indicates flush mounting design.

Recommendations and Usage Notes:
- Suitable for linear motion applications requiring precise bearing fit.
- Selection should consider dimensional compatibility with mating components.

This summary captures the essential technical specifications and dimensional data for HASCO linear ball bearings without centering projections, facilitating correct selection and application in mechanical assemblies.
