Power Transmission Seals
E Rail Trans supplies a robust selection of SKF radial shaft seals, engineered to maintain critical sealing between rotating and stationary components. These seals consist of two core elements: a cylindrical outer surface for static sealing against the housing bore, and a precision sealing lip that dynamically and statically seals against the shaft. Their design ensures a defined radial load for effective sealing performance under diverse conditions.

Reliable Sealing Solutions for Demanding Applications
As an authorized reseller of SKF seals, E Rail Trans delivers high-performance sealing solutions that safeguard equipment, improve efficiency, and extend component life. With poor sealing responsible for costly contamination and system failures, choosing the right seal is essential for reliable operation.
Track Pin Seals
SKF Trackstar seals are engineered for oil-lubricated track chains in off-highway equipment, delivering durable sealing performance in demanding environments. Positioned on the pin connecting a pair of chain links, these seals retain oil, exclude contaminants, and minimise bushing and pin wear.
Key Features & Benefits:
Polyurethane sealing ring with nitrile rubber energiser for optimal sealing performance
Ribbed inner diameter for improved oil distribution and lubrication
Heavy-duty version with metal reinforcement for severe conditions
Spacer ring compatibility ensures precise fitment and optimal lubrication flow
Quick and easy installation
Compatible with most common sealed and lubricated track pin systems
Available Versions:
Standard SKF Trackstar Seal – With polyurethane ring and nitrile energiser
Heavy-Duty Trackstar Seal – Reinforced with a metal ring for high-rigidity applications
Metal face seals
Durable Sealing Solutions for Extreme Environments
SKF metal face seals are built to perform in the harshest operating conditions—where exposure to dirt, mud, water, and abrasive materials is constant. Designed for low circumferential speeds, these seals offer superior reliability by keeping contaminants out and lubrication in.
Originally developed for off-road and tracked vehicles, SKF metal face seals are now trusted in multiple high-demand sectors, including:
Mixers and sand treatment equipment
Conveyors and construction machinery
Agricultural machinery
Washing and grinding systems
Ore dressing and mining operations
Their rugged design and robust materials make them ideal for applications where conventional seals fail.
V Ring Seals
SKF V-ring seals are axial shaft seals designed to protect bearings and rotating components by excluding contaminants such as dust, dirt, and water. These seals also retain lubrication, making them a versatile choice for a wide range of industrial applications.
Available in a broad selection of stock sizes, V-rings can also be custom-manufactured for shaft diameters over 2,000 mm or unique operating requirements.
V-Ring Options:
All-Rubber V-Rings – Standard design, offering excellent flexibility and ease of installation
MVR Seals – Metal-cased V-ring seals for added rigidity and performance in more demanding environments
Whether you’re sealing in light-duty applications or heavy industrial systems, SKF V-ring seals deliver reliable axial sealing and extended equipment protection.

Axial Clamp Seals
SKF axial clamp seals are designed specifically for large and very large shaft diameters, offering robust sealing in harsh environments. They are ideal as primary or secondary seals in applications where excessive exposure to solid or fluid contaminants is present. Unlike typical rotary seals, axial clamp seals remain stationary and seal axially against a rotating counterface.
Manufactured from profiled strips of non-reinforced nitrile rubber, these seals are secured in place with durable stainless steel band clamps, ensuring reliable fitment and performance.
Key Features:
Designed for shaft diameters ranging from 150 mm to 4,600 mm (5.9 in. to 181 in.)
Suitable for both inch and metric-sized shafts
Effective sealing solution for contaminated or abrasive conditions
Easy to install and maintain
Machined Seals
SKF machined seals offer a highly adaptable and fast-response sealing solution for a wide range of fluid power and power transmission applications.
