What groove tolerances does Frigate recommend for optimal Oil Seal Retaining Ring fitment?

Frigate recommends groove width and depth tolerances within ±0.025 mm based on DIN 471/472 standards. This ensures proper seating and axial retention without overloading the ring. Groove wall angles are also controlled to prevent stress concentration. Custom groove profiles can be designed using FEM analysis if needed.

Name: Oil Seal Retaining Ring | Shaft Seal Locking Element – Frigate
Price: 249.00 USD
Availability: InStock

Oil Seal Retaining Ring provides positive axial restraint to radial shaft seals subjected to fluctuating loads and vibration-induced displacement. Precision-machined ring geometry maintains uniform clamping force across the housing bore, ensuring seal integrity under high dynamic pressure and torque transients.

Inside Diameter (ID)

10–500 mm (±0.05 mm for ID <100 mm, ±0.1 mm for ID ≥100 mm)

Outside Diameter (OD)

15–550 mm (±0.1 mm for OD <150 mm, ±0.15 mm for OD ≥150 mm)

Thickness

0.5–3.0 mm (±0.02 mm for t <1 mm, ±0.05 mm for t ≥1 mm)

Material Type

Carbon Spring Steel (SAE 1074/1095), Stainless Steel (AISI 301/304), Phosphor Bronze (C51000)

Cross-Section Shape

Rectangular (90%), Circular (Wire-Type), or Custom (e.g., L-Shaped for groove retention)

Product Description

Oil Seal Retaining Ring maintains consistent radial interference despite thermal gradients between housing and shaft materials. Engineered clearances and material thermal expansion coefficients are matched to limit seal movement under repeated heat-soak and cooldown cycles common in rotating assemblies.

Finish/Coating

Zinc Plated (5–8 µm), Passivated (Stainless Steel), Black Oxide, or Uncoated

Hardness

Spring Steel – 40–50 HRC, Stainless Steel – 30–40 HRC, Phosphor Bronze – 75–85 HRB

Gap/Overlap

Internal Rings – 0.5–2.0 mm gap, External Rings – 1.0–3.0 mm overlap (adjustable per DIN 471/472)

Applicable Standard

DIN 471/472 (Metric), JIS B 2804, ASME B18.27 (Inch Series)

Certification Standard

ISO 9001, RoHS, ASTM A313 (Spring Steel), ASTM F1941 (Retaining Rings)

Technical Advantages

Oil Seal Retaining Ring restricts axial float within ±0.02 mm by maintaining tight groove engagement and radial spring force. This eliminates micro-movements that degrade sealing lips and ensures proper contact pressure over long-duration operation at elevated speeds.

Oil Seal Retaining Ring is manufactured using corrosion-resistant alloys, such as AISI 316 or Inconel, depending on exposure to lubricants, fuels, or salt-laden atmospheres. Each ring material is selected for mechanical strength and chemical compatibility with operating environments.

Industry Applications

Automotive Transmission Systems

Oil Seal Retaining Ring secures radial shaft seals in automatic transmissions to prevent seal displacement under torque and hydraulic pressure fluctuations.

Industrial Gearboxes

Oil Seal Retaining Ring maintains seal position in high-speed gearboxes, ensuring constant lubricant retention during variable load transmission cycles.

Hydraulic Pump Assemblies

Oil Seal Retaining Ring holds rotary seals in axial alignment under pulsating pressure, preventing internal leakage and seal extrusion failures.

Electric Motor Housings

Oil Seal Retaining Ring retains sealing elements on motor shafts to prevent ingress of contaminants during continuous high-RPM operation.

Aerospace Actuation Units

Oil Seal Retaining Ring supports shaft seals in servo actuators exposed to rapid pressure shifts and extreme temperature cycling environments.

Marine Propulsion Systems

Oil Seal Retaining Ring secures seals in propulsion shafts operating in submerged, saltwater conditions with continuous torsional and axial loads.

Groove Compatibility and Installation Efficiency

Oil Seal Retaining Ring is designed to fit standardized housing grooves without requiring special machining or retaining hardware. Precision tolerances allow for consistent seating and controlled hoop stress during press-fit or snap-fit installation processes.

Oil Seal Retaining Ring is optimized for high-cycle fatigue conditions where rotational imbalance and shaft harmonics induce fluctuating loads. Stress-relief features and surface treatments reduce crack initiation risk and extend service life beyond standard clip-type rings.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure concentricity in Oil Seal Retaining Rings for high-speed rotating assemblies?

Frigate uses precision CNC turning and in-process gauging to pflegen concentricity below 10 microns. This prevents eccentric loading on the shaft seal at high RPM. Consistent radial balance reduces shaft wobble and seal wear. The result is improved sealing reliability in dynamic applications.

How does Frigate select materials for Oil Seal Retaining Rings in corrosive environments?

Material selection is based on fluid exposure, temperature range, and mechanical loading. Frigate offers stainless steels (AISI 304/316), carbon steels with plating, and high-performance alloys like Inconel. Each material undergoes salt spray or chemical compatibility testing. This ensures long-term performance in aggressive service conditions.

What methods does Frigate use to verify load-bearing capacity of Oil Seal Retaining Rings?

Frigate performs axial push-out testing using servo-hydraulic rigs to simulate dynamic pressure loads. Finite element models are used to predict stress distribution in the ring groove. Test data is correlated with simulation for validation. This approach ensures that ring deformation and seal displacement stay within design limits.

How does Frigate address fatigue failure in Oil Seal Retaining Rings used in cyclic load environments?

Frigate uses shot peening and surface conditioning to increase fatigue resistance in high-cycle environments. Stress-relieving operations are applied after forming or machining. Fatigue life is evaluated using strain-life analysis under simulated duty cycles. This guarantees durability in systems with continuous torsional vibration.
