Accurate Levelling - With the range of Precision Levelling Adjusters

The patented range of Precision Levelling Adjusters (PLA) provides a means of accurate levelling, location, spacing and precise adjustment.

The range has been developed for use with Machines, Motors, Drive Shafts, Machine Cradles, Bearings, Production Equipment, and a multitude of other applications.

The PLA provides the user with a universal re-usable adjuster that can replace complicated and expensive specials or in the most simple of situations the time consuming use of shims.

The PLA can quickly and safely solve most adjustment problems.

Features Include:-

• Precision Adjustment
• Accomadates Heavy Loads
• Safety end-stop, eliminating over adjustment
• Vertical and Horizontal Adjustment catered for Angular Compensation for non-parallel surfaces
• Accommodate or replace bolts from M4 to M48
• Cater for Loads up to 526 kN (118,000 lbf)

• Suitable for both static and dynamic loads
• Replaces complicated and expensive specials

General Overview

The Precision Levelling Adjusters (PLA) consists of :-

A fine threaded mounting top (Item 1) nesting within an internally fine threaded nut base (Item 2). Levelling and adjustment is accomplished with the use of spanner wrenches.

The integration of a safety end-stop, (Item 3) eliminates over adjustment, and ensures that the total load is maintained through the entire levelling distance.

The fine thread design permits precise adjustment.

Once the necessary level of adjustment has been reached, it is set firmly by tightening the mounting or anchor bolts passing through the central hole of the unit.

Re-adjustment is easily accomplished by simply relaxing the mounting bolt, adjusting the PLA, and once again tightening the mounting bolt. With a motor resting on the PLA, tightening a drive belt is simple, loosen the mounting bolt, level the motor with the spanner wrenches, and re-tighten the bolt.

The entire range of products is available in the following materials:

• Mild Steel Alloy Steel - 708M40 (EN19) - 42CrMoV - 1.7225 (Finish - Zinc Plated - Chromated)
• Stainless Steel A1 303S31 - X10CrNiS 18.9 - 1.4305
• Stainless Steel A1 316S31 - X5CrNiMo 17.12.2 - 1.4401

Product Range

The HVS series offers the greatest range of adjustment with h of 15mm to 55mm

The HVSK series incorporates a locknut which enables the adjuster to be secured in a pre-set position making it ideal for dynamic load applications or as a locater for pre-established height adjustment after disassembling.

The NAE series has the same functionality as the HVS range but its compact design is intended for use where space is a limitation. Adjustment h is limited to between 4mm and 14mm.

The application of the Ball Head Precision Adjuster - KAE - facilitates precise adjustment of nonparallel surfaces with a maximum adjustment angle of 4°.

The Ball Shim - KAS - has the same non-parallel compensation function as the Ball head Precision Adjuster KAE. The Ball Shim KAS (Pos A) and the HVS provides a solution when assembling angled surfaces up to an angle of inclination of = approx. 4°. (Note: - When exceeds 1° out of parallel, an additional KAS (Pos B) is recommended to align and support the screw/bolt head.)

The XY series facilitates both vertical and horizontal adjustment. In application, it is often found that in addition to vertical adjustment, a slight horizontal adjustment is also required. It is important to obtain an accurate alignment in both directions. For this purpose a new base has been developed, which allows a two-axial adjustment. The XY series is available in the following PLA styles HVS, HVSK, NAE and KAE.

Accessories

The DS series of Spacers provides a means of increasing adjustment when the standard travel h is insufficient. The HS series of Spanners Wrenches are used to adjust the range of PLA
