PRODUCT LINE
Internal Retaining Rings: 4 standard inch series of rings designed to fit common bore sizes. The UR series is the lightest duty series, and the RRN series if the heaviest. RR is the most commonly used series of retaining rings. The RRN series ring were designed to fit into the same groove as N5000 series rings.

External Retaining Rings: 4 standard inch series of rings designed to fit common shaft sizes. US is light duty and RSN is heavy duty. RSN rings were designed to fit into the same groove as 5100 series rings.

Metric Internal Retaining Rings: These three series are made to fit common metric bore sizes. ZRM is medium duty and ZRH is heavy duty.

Metric External Retaining Rings: These three series are made to fit common metric shaft sizes. ZSM is medium duty and ZSH is heavy duty.

The unique design and precision-fabrication of Spirolox Retaining Rings gives you greater freedom of design and speeds product assembly by eliminating excess machining and reducing the number of parts. The Spirolox continuous, uniform retaining shoulder obsoletes the need for machined shoulders, counterboring, threading, drilling and other complicated and costly processes. Saves labor, material, weight and space.

360° RETAINING SURFACE
Spirolox rings are fabricated from high-quality, rectangular carbon spring steel or "302" stainless steel coiled on edge to form a 360° retaining surface. This creates a ring with exceptional strength and stability. And because the coil is thin in section it provides the flexibility needed for easy installation and removal. They can be manufactured in sizes from 3/8 inch diameter to 85 inch diameter.

DESIGN OPTIONS
To further increase your freedom of design, a number of optional variations are available:

  1. The height of the continuous uniform retaining shoulder can be varied for special applications without incurring tooling costs.
  2. Rings of varying thickness can be fabricated by either varying the thickness of the material and by increasing the number of turns.
  3. Use of thin section material permits the forming of tabs, prongs and other devices for meeting special assembly or disassembly problems.
  4. Use of multi turn sections permits greater flexibility during installation.
  5. Rings can be fabricated from specialty materials and given a variety of finishes.
SPEEDS PRODUCT ASSEMBLY
The flexibility and the simplicity of design make Spirolox easy to handle, no special tools are required to install or remove the rings. The reduction in the number of machined parts needed for a retaining application also contributes to quick and easy installation.

Spirolox Retaining Rings can be assembled quickly by manual methods, and they lend themselves readily to semi-automatic methods for high-volume production.

OFF-THE-SHELF DELIVERY
Spirolox stocks popular sizes of Spirolox Rings for both internal and external applications. Catalog sizes to fit shaft and bore diameters range from 7/16 inch up to 15 inches, and many are ready for prompt shipment off the shelf.

Custom rings can be designed to user specifications and forecasted usage.

QUALITY ASSURANCE
Some of the most modern equipment to be found in American industry given Spirolox the opportunity to maintain a high quality product in high-volume production.

Automatic equipment coils, crimps, notches and cuts-off Spirolox Retaining Rings on one machine. Other modern machinery in the hands of skilled operators keeps production moving form raw materials storage to packing and shipping.

Continuous quality-control analysis and monitoring both in the laboratory and on the production line makes sure that uncompromising quality is maintained.

Spirolox maintains controlled certification of raw materials, lot segregation on in-process materials and of finished inventory. Certification of conformance for materials used and/or for finished parts are available on request. Certifications for special requirements such as MIL-R-27426 must be requested at the time order is placed.

TECHNICAL ASSISTANCE
Spirolox's Design and Engineering Staff will be glad to render technical assistance in choosing the proper retaining rings for your particular application.

The staff is also at your service to render engineering, technical and design assistance for the development of special rings to meet unusual requirements.

Spirolox understands spiral wound retaining rings better than anyone in the business. We are the original patent holders, and have continued to develop and improve our rings over the years. We have developed formulas and countless data to verify those formulas, and have combined them both with our computer system to accurately design the right ring for your application.

METRIC
Spirolox supplies rings in conformance with SAE MA4035 MA4016, and MA4017.
