Application Examples
Rubber boot
A 2-Turn Spirolox Retaining Ring clamps the rubber boot onto the groove making for a nearly perfect seal when the boot is filled with grease. The ring has been deburred so it will not tear into the rubber.
Pneumatic Fitting
An economical (without removal notches or offset) 2-Turn Spirolox Retaining Ring creates an ID/OD lock, permitting the 360º rotation of the nut. This permanent assembly is commonly used to hold two components together.
Conduit Connector
In this unique application, a Dished Retaining Ring was designed with sharp edges, to bite into the conduit it holds in place. The clamping force of the ring to the conduit (not shown) is achieved by screwing the nut. This decreases the ring's diameter as it advances in a tapered bore.
Gear Bracket
The worm gear shaft is held in place and preloaded using a 2-Turn Smalley WaveRing. The WaveRing fits an internal groove and the waveform in the ring allows the gear/shaft to float axially as the gear rotates.
Ratchet Wrench
This Single-Turn (it is actually 1 1/2 turns) External Retaining Ring retains the internal mechanical components of the ratchet wrench. The additional 1/2 turn provides that little extra strength needed to prevent the ring from dislodging when the wrench is dropped.
Cylinder Housing
The Hoopster Retaining Ring in this application allows for a shallow groove in the cylinder housing without compromising the ability to have high forces applied to the Hoopster. Because the cylinder is thin, a normal retaining ring groove could not be used.
Bike Lock
Tamper-proof ring holds the lock assembly within its housing. The ring is considered tamper-proof because of reversed removal notches. Also, having a heavy cross-section makes the ring nearly impossible to remove.
Pressure Gauge
A retaining ring designed in a shallow groove exerts very light pressure on the glass lens in this pressure gauge. This single-turn retaining ring design provides the optimum load without breaking the glass.
Gear Assembly
External 2-Turn retaining ring prevents the pinion shafts from spinning when the gears are rotating. The Spirolox ring snaps securely on the groove and the ring?s radial wall is designed to extend radially outward, clearing the four flat pinion shaft pins by 0,50 mm.
Actuator Valve
High thrust capacity was needed and a constant section ring was selected to absorb the occasional shock loading of the pistons.
Pneumatic Clutch
The internal components of this clutch are held in the housing using a heavy-duty constant section ring ring. Field servicing was often necessary and the snap ring was the ideal solution to the design requirement.
Hose Fitting
To keep the cap on the fitting, a single-turn retaining ring is located in a shallow internal groove. The wall thickness of the cap is small, so the ring was designed with square corners to operate in a very shallow groove.
Right Angle Drive
Constant section rings secure the bearing assembly by providing removable shoulders in the bore. This simplifies the design of the gear box and replaces costly flanged end plates.
Air Vent
Single-turn, light-duty retaining ring fits tightly in the internal groove of a plastic air vent. Ring ends are dimensioned close together, providing nearly complete 360º ring support.
Pulley Idler
2-Turn retaining rings provide 360º side walls as sides of the timing belt pulley. Design eliminates costly pressed-on stamped side walls. For belt replacement one ring can be easily removed.
Belt Pulley
Three hold down screws and a 2-Turn Spirolox Ring form a bi- directional shoulder. The shaft is inserted through the pulley and the retaining ring rests on the pulley face securing the shaft in one direction. Movement is prevented in the other direction with the three screws clamping down onthe ring.
ID/OD Lock
Single-turn retaining ring operates in an internal and external groove at the same time, commonly referred to as an ID/OD Lock. In thisnapplication, the ring fits tight on the body (shaft) groove and extends radially into the nut (housing). This allowsthe nut to spin freely but not come off the body.
Hip Replacement
A titanium Spirolox Retaining Ring is used in this hip replacement application to secure the shell and the liner together to form the socket of the new hip. The manufacturing process allows for the economical production of special alloy products.
