Procureit has access to the largest supply of circlips in Australia and New Zealand. Technical specialists are on hand to solve your circlip application requirements. Special items can be sourced or manufactured to your specifications.

Standard External Circlips DIN 471 D 1400 Metric
Standard External Circlips N1400 American
The most common form of axially fitted circlips for bores with grooves. The circlip has a large free diameter and gap width, consequently it fits more tightly into the groove and provides higher and more uniform thrust load capacity.Lugs with holes are provided for rapid fitting or removal with circlip pliers.
(Standard circlips are available in Stainless Steel)

Standard Internal Circlips DIN 472 D 1300 Metric
Standard Internal Circlips N1300 American
The most common form of axially fitted circlips for bores with grooves. The circlip has a large free diameter and gap width, consequently it fits more tightly into the groove and provides higher and more uniform thrust load capacity.Lugs with holes are provided for rapid fitting or removal with circlip pliers.
(Standard circlips are available in Stainless Steel)

Heavy Duty External Circlips DIN 471 Metric
Heavy Duty External Circlips N1460 American
Design is based upon the standard external series but with increased thickness and in the case of the American series increased section depth. Heavy duty Circlips are used to withstand shock loads and also to resist conical deformation where, for example, large abutment radii are present.

External Circlips with Increased Abutment to DIN 983
Axially fitted circlips for shafts with grooves. Similar in design to Din 471 Circlips, but with additional lugs evenly distributed around the circumference. This is especially useful for maintaining good contact with radiused or chamfered components. High axial loading capacity.

Internal Circlips with Increased Abutment DIN 984
Radially fitted circlips for bores with grooves. Similar in design to DIN 472 Circlips, but with additional lugs evenly distributed around the circumference for more effective securing of machine parts with chamfers and large radii. High axial loading capacity.

Standard E Type Circlips RSM incorporating DIN 6799 & BS 3673/2 Metric Series
Standard E Type Circlips N1500 American incorporating BS 3673 part 2 and MIL-R_21248/MS 16633
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 resultingin sharply reduced assembly costs. Only the groove size is critical with this type of circlip, the shaft diameter can be varied widely.
(Also available in Stainless Steel)

Crescent Rings: SSM Metric
Crescent Rings: N1800 American
Radially fitted circlips for shafts with grooves. Crescent Rings provide a shallow but uniform shoulder on relatively small shaft diameters. Higher resistance to thrust loads than standard 'E' type circlips. Neat appearance and suitable for applications where small clearance dimensions are important.
(Certain sizes are available in Stainless Steel)

Grip Rings: M1440 Range
Grip Rings: GRP Range
Self locking axially fitted circlips for shafts without grooves. Grip Rings have a large section height resulting in a high gripping pressure. Moreover, the tapered section design ensures even contact when fitted. As this circlip is not stretched beyond its elastic limit during fitting or removal it may be re-used as often as required without causing damage to the shaft.
(Certain sizes are available in Stainless Steel)

'U' Type Circlips
Radially fitted 'U' type circlips for shafts with grooves. Average axial loading capacity. Easy to remove manually or with make-shift tools.

Plain Wire Rings
Radially applied circlip which provides a high shoulder and more peripheral abutment. Designed to tolerate wide groove diameter variation. Easily fitted and removed.

External Snap Rings
Axially fitted snap rings for shafts with grooves. Mainly used for the assembly of needle bearings, needle cages and sealing rings.

Internal Snap Rings
Axially fitted snap rings for bores with grooves. As with SWM snap rings these are mainly used for the assembly of needle bearings, needle cages and sealing rings.

External Snap Rings (DIN 5417)
Axially fitted snap rings designed for use with roller bearings. The grooved bearings conform to DIN 616. The application of roller bearings with snap rings gives the advantage of a smooth-bored housing and a shorter overall axial length.

External Snap Rings (DIN 7993 Part A)
Axially fitted snap rings for shafts with semi-circular grooves. Manufactured in hardened round section wire.

Internal Snap Rings (DIN 7993 Part B)
Axially fitted snap rings for bores with semi-circular grooves. Manufactured in hardened round section wire.

Circlip Pliers: External - Internal - Grip Rings
Designed to grasp the circlips securely by the lugs during fitting and removal. Precise alignment of the tips prevents the circlips from springing loose, and permits rapid fitting or removal even by unskilled labour.

Circlip Applicators and 'Eurobase' Dispensers
The use of applicators and 'Eurobase' dispensers in conjunction with stacked 'E' Type circlips to DIN 6799 has the following advantages:

Circlip Materials

The standard material for all circlips with the exception of some small external types which are made from beryllium copper, is carbon spring steel. Other materials are available on request including stainless steel (DIN 1.4122), phosphor and beryllium copper.

It should be noted that parts made from special materials, cannot be guaranteed to meet the thickness specifications of standard parts, due to wider tolerance bands available on raw materials. The nominal thicknesses are maintained but allowance should be made for additional thickness tolerances.

Care should be taken when specifying special materials that no galvanic interaction between the circlip and the groove material is likely to occur. This is usually only a problem when the assembly is in contact with conductive atmospheres.

Plated and Other Finishes

Phosphate and oil is the standard finish on most circlips, the remainder being self finish and oil. Where improved properties or appearance are required for operation in corrosive environments plating provides additional protection.

Zinc plated finish, with either clear or yellow chromate passivation, is available and may be electrolytic or mechanical at our discretion. Plated thickness can be 6 micron or 12 micron and will increase the overall thickness of the circlip.

It is essential to select the finish required with a view to the operating conditions including the groove material or finish, since some combinations may actually accelerate corrosion.

Coloured lacquer finishes, for identification purposes, are available subject to enquiry as are copper flashed.

Procureit has the capacity to handle all requests from 'one off specials' to complete circlip inventory supply to mines, mills and food industry customers.
