Specifications:
The document outlines the specifications for replacement liners used in QCTM bushings, as per US Patent No. 5,882,695. It includes a detailed list of liner sizes and their corresponding fit bushings, categorized by inner diameter measurements ranging from 1/2 inch to 2 inches.

Procedures:
The document does not explicitly detail procedures but implies the use of these liners in conjunction with specific bushings for optimal fit and function.

Norms and Standards:
The liners are made from CA954 Solid Bronze with a hardness of 170 Brinell, ensuring durability and performance. The document also mentions the use of a spanner wrench, specifically the SW-100 Adjustable Spanner Wrench, made from hardened steel, indicating a standard tool for installation or adjustment.

Recommendations:
For each inner diameter category, multiple liner options are provided, suggesting flexibility in application depending on specific requirements or constraints.

Key Data from Tables:
The tables list liner numbers and their corresponding fit bushings for various inner diameters. For example, for a 1/2 inch diameter, the liner BL50L1.50 fits the GQC50 bushing. This pattern continues for larger diameters, providing a comprehensive guide for selecting the appropriate liner and bushing combination.

Critical Information:
It is crucial to select the correct liner and bushing combination to ensure proper fit and function. The use of the SW-100 Adjustable Spanner Wrench is recommended for adjustments, highlighting the importance of using the right tools for maintenance and installation.
