ABEC 5 bearings have either nylon/graphite retainers or new 1022 steel cages for improved strength. Depending on the usual duty for the specific bearing size, we now choose either 1022 steel or nylon/graphite to better suit the types of forces and duty the bearing most likely will handle. With the advent of thru-axles and asymmetric disc brake forces, 1022 steel retainers better align the balls with axial forces. Nylon/graphite retainers perform smoothest under strictly radial loads. Grease Type

A metal-on-metal screeching at low speeds is usually diagnosed as brake pads that need to be replaced. While this is the reason in many cases, if you know your brakes are new or don’t need to be replaced, you can usually narrow it down to your wheel hub. A wheel hub that has lost its grease and is wearing the bearings with no lubrication will produce a loud metal-on-metal sound at low speeds.

Durability & Performance - Hub bearings use high-quality rubber to optimize the seal’s performance and durability against high temperatures and weathering.

To meet the ABEC-5 standard, bearing design must pass all tests, which include noise testing at high RPM, extremely close tolerances for I.D. and O.D., roundness of ball, trueness of the races and micro surface finishes of balls and races.C-3 Clearance

Quality Control - In order to increase longevity and resist abrasion, GSP’s ball bearings are spaced precisely to the appropriate clearance for smooth rotation.

This specification describes the internal clearance between the bearing and its race. For example, in a 10-18 I.D. bearing, our standard is 11-21 micrometers where as others use 11-25 micrometers.All across the board, our bearings have higher standards of tolerance to ensure superior performance.C-N Clearance

We also offer our new Dual Seal Abec-5 bearings with CN Internal clearences for manufacturers that use tighter tolerences within the given component. In a 10-18 I.D. bearing, our internal clearance standard is 3-12 micrometers.All across the board, our bearings have higher standards of tolerance to ensure superior performance.

GSP offers some of the highest quality wheel hubs in the industry. GSP offers both wheel hub and knuckle hub assemblies.

ABEC 5 bearings are now using the recently improved formula of Mobil XHP 222 grease. The new formula performs better for all situations that we have ever tested. This includes protection against the elements of rain, dirt, muck, and sand over extended periods of testing, far outlasting previous greases we have tested. The new Mobil XHP 222 grease will not separate over time or with intense heat such as car storage on a hot day. It also can resist very low temperatures better than the competition such a snow or ice environments. The ABEC 5 Standard

Vulcanization Process - All Hub Assemblies go through a vacuum vulcanization process to enhance the structural integrity of the seal and rubber components.

A wheel hub, or wheel bearing, is a component that keeps your wheel attached to your vehicle while allowing the wheels to turn freely for safe steering. This is also vital to a vehicle’s anti-lock braking and traction control systems. The wheel hub bolts to the steering knuckle and allows for a brake rotor and wheel to be attached to it via studs and lug nuts. When your wheel hub goes bad, it can cause various issues that affect your steering and acceleration. Today, we will look at 4 signs of a bad wheel hub.

Enduro Bearings uses highest quality 52100 High Carbon Chromium Steel Alloy race material from Japan. There are many suppliers of 52100 material, but they do not all necessarily provide the same quality material. The material for Enduro steel races starts with and extremely-pure, vacuum de-gassed chromium steel alloy that is then hardened to Rockwell HRC 64 by multiple rounds of heat and cryogenic treatment. The material is then cut to size and the races are machined, ground and polished to a mirror finish for ABEC-% precision and noiseless movement.Nylon/Graphite and Steel Ball Retainers

If your wheel bearing has begun to wear down and metal-on-metal contact without enough grease to lubricate it properly, you will experience vibrations in your steering wheel. As the metal bearings start to wear down, there will be more play in the wheel bearing, causing them to vibrate.

If you notice an unusual noise coming from your wheel at moderate speeds, a few things could be wrong. Your lugs could not be tight, your brakes may be dragging, or your wheel bearing may be bad. It is often hard to diagnose a noise at moderate speeds, but if you have inspected your brakes and checked your lug nuts, which are both good, you most likely have a bad wheel hub.

Enduro ABEC 5 bearings use LLB type seals and our new LLU/LLB seals. The LLB seal is a light contact double lip groove seal. The LLU seals is a medium contact double lip groove seal and is Grey in color to easily identify. This Grey LLU seal should face out towards the elements for improved sealing and water protection. The Black color LLB seals are internal and help protect while spinning smoothly with low friction.

Premium Materials - To ensure a smooth surface, free from defects, burrs, and cracks, all bearing housings are manufactured with polyamides for added impact toughness and age resistance.

Lastly, if your Anti-Lock Brake Light or Traction Control Light illuminates and you are experiencing vibrations in your steering wheel, you most likely have a bad wheel bearing. In most modern cars, a wheel bearing that has gone bad will cause the system to trip. This will cause an ABS speed sensor code to be stored and your dash light to illuminate to indicate that you have an issue.
