Ruland Two Piece Aluminium Shaft Collar, Clamp Screw Fastening, 20mm Bore, 45mm OD, 10mm Width ENSP45-20MM-A

Ruland ENSP45-20MM-A is a high precision two piece aluminium shaft collar designed for use in mechanical power transmission and industrial machinery applications. Featuring a 20mm bore, 45mm outside diameter, and 10mm width, this collar uses a clamp screw fastening mechanism that provides strong hold without marring the shaft and allows for easy removability and indefinite adjustability.

The thin line design reduces overall weight, making it effective in confined spaces and equipment requiring lightweight components. The double wide design ensures enhanced load distribution and stability during operation.

Critical for accurate alignment tasks, the collar offers tightly controlled face to bore perpendicularity with a total indicator reading (TIR) of ≤ 0.002". This precision is essential when used as a load bearing face, mechanical stop, or for mounting components such as gears or bearings.

Manufactured under stringent standards including RoHS3, REACH compliance, and adhering to DIN 912 12.9, the product guarantees environmental safety and high mechanical performance. The collar has a bright finish enhancing corrosion resistance and aesthetic appeal.

The threaded bore size M4 x 12 provides secure fastening with standard screws allowing easy maintenance and assembly operations. Application areas include conveying systems, machine building, automation, and various industrial equipment requiring shaft locking, spacing, and position fixing.

The two piece design allows installation or removal without shaft damage. Clamp screw fastening offers flexibility and strong grip. Aluminium construction offers lightweight and corrosion resistance. Precise perpendicularity (TIR ≤ 0.002") ensures reliable mechanical alignment.

Double wide design enhances load handling capability. Bright finish improves durability and appearance. Compliant with RoHS3, REACH, and DIN 912 12.9 standards. M4 x 12 threaded bore size enables standard screw compatibility.
