Circlips or Retaining Rings

Circlips

Circlips are used to prevent lateral movement. They are used as retaining rings on bearing assemblies and are manufactured using semi-flexible metal ring. These products are in a shape of a circle with a clip and are open from one end. 

Constructed as curved beams of uniform strength, the radial width is reduced towards the free ends so that a constantly round shape is maintained throughout continuous use. This form of circlip often used in assemblies subjected to strong centrifugal forces, is also secure against high rotational speeds. Lugs with holes are provided for rapid fitting or removal with circlip pliers.

Circlips now available in High Strength and Corrosion Resistance Aerospace Grade.

SS 1.4532-Aero Grade provides exceptional strength combined with Corrosion resistance that is essential for the Aerospace industry.

The following types are available:

External Circlips – DIN 471 

Circlips are used to prevent lateral movement. They are used as retaining rings on bearing assemblies and are manufactured using semi-flexible metal ring. These products are in a shape of a circle with a clip and are open from one end.

The most common form of axially fitted circlips for shafts with grooves.

Constructed as curved beams of uniform strength, the radial width is reduced towards the free ends so that a constantly round shape is maintained throughout continuous use. This form of circlip often used in assemblies subjected to strong centrifugal forces; is secure against high rotational speeds. Lugs with holes are provided for rapid fitting or removal with circlip pliers.

Internal Circlips – DIN 472

Type B type internal circlips are used to prevent lateral movement of assembly components in a bore. These internal circlips are manufactured using high-grade spring steel or Stainless Steel. We offer these products in a huge variety of sizes, dimension and thicknesses to meet specific needs of our clients. Our complete range is strictly tested on the basis of different parameters.

These products are suitable for most normal engineering applications as these simply act as a rigid shoulder within a bore.

Type E Circlips – DIN 6799

We offer a comprehensive range of E type circlips.

The most common form of radially fitted circlips for shafts with grooves. Provide a large shoulder on a relatively small shaft diameter. This range can be supplied stacked on rods for use with applicators and dispensers for rapid installation, thus resulting in sharply reduced assembly costs.

Only the groove size is critical with this type of circlip, the shaft diameter can be varied widely.

Snap Rings – DIN 9925 and DIN 9926

Axially fitted snap rings for shafts with semi-circular grooves. These are mainly used for the assembly of needle bearings, needle cages and sealing rings. 

They are predominantly used in semicircular grooves in conjunction with quarter-circle coverage of the located mating component.

Applications:

  • Securing gudgeon pins (special shapes)
  • Gear systems
  • Automotive engineering
  • As auxiliary installation elements
  • In the fittings industry

Push on Retaining Washers – Starlock or Push Lock Washers

Push Lock or Push on or Starlock washers are used to prevent lateral movement. They are used as retaining rings on bearing assemblies. 

No groove required—press these rings onto the end of a shaft. Use them on unhardened shafts that are softer than the push ring. The ring bites into the metal to form an interference grip, so expect minor scratching.

  • Durable and secure fastening
  • Replaces circlips, split pins, bolts and nuts
  • No preparatory work on the shaft necessary
  • Cost-effective assembly solution – enables competitive costing
  • Simplifies the design
  • No thread cutting required
  • Automated assembly process possible
  • RoHS-compliant

External fixing washers for use not only on precision-machine shafts but also on tubes, cast parts, plastic shafts and studs. Available for shaft sizes 0.8mm to 10mm diameter.

The washers are held in an assembly tool and simply pushed on to the shaft causing the prongs to grip the shaft tightly, locking the washers in place with initial tension

Starlock fasteners simply push on to a shaft giving an instant fix and grip, thus eliminating costly threading, drilling or grooving operations. Once fixed in position, the push-on fastener is so secure that it cannot be removed without destruction. High carbon spring steel is specially heat treated to ensure secure holding quality.

Material: Spring Steel

Retaining Washers

A Plastic Retaining Washer is primarily used to hold screws and bolts in place during assembly and have a design that grips the outside of screw or bolt shank. Also known as an Anti Loss Washer, they provide insulation, cushioning and spacing. They help insulate fastening assemblies from moisture and electricity.

This washer range includes options with internal and external teeth with a tapered design. The washer slides/assembles on to the screw (or bolt) and is retained by the screw once assembled. The washer cold forms and fully enters the pitch of the screw to provide sealing.

These washers allow for preliminary mounting of the screw (or bolt) before securing with a nut. They are ideal when pre-assembly of the screw and washer is required.

These Washers have specially configured internal shape designed to grip the outside of the screw shank/threads.
