Scooter bearings (Kick scooter bearings, Electric scooter bearings, Skateboard bearings) are widely used in many applications on recreational scooters/skateboards including; mini bikes, ATVs, dirt bikes, skateboards, go karts, kick scooters, electric scooters and street scooters. You will always find the right scooter/skateboard bearings here for your application.
These ball bearings for scooters/skateboards with double/single-sealed (2RS or RS suffix) or double/singled-shielded (ZZ or Z suffix). Bearing precision grade has ABEC-3, ABEC-5, ABEC-7.

To address the changing landscape of bicycle headsets, a group of leading headset manufacturers have collaborated to develop a standardized "language" for headset fitment. The new Standardized Headset Identification System (S.H.I.S.) creates a common language for describing modern bicycle headsets. The system provides comprehensive and scalable headset fitment information in a standard format; making it easier to communicate headset requirements based on frame and fork interfaces.
The Standardized Headset Identification System (S.H.I.S.) incorpo...
Garage Door Rollers (steel rollers and nylon / plastic rollers) are made up of stem / shaft and rollers.
Shaft / stem was made of carbon steel or stainless steel. Roller was made of carbon steel, stainless steel or nylon.
If you have special requirements, we can use standard shielded deep groove ball bearings to replace steel balls.
For carbon steel shaft / stem and roller, it will be harded and zinc-coating finishing.
Our garage door rollers could be used in 2" track and 3" track. Welcome to custom application!
** Designed for durability and a long trou...
Ball Transfer Units are made up of housing, rolling elements (small steel balls & big steel balls / plastic balls), seal that means consisting of a large solid high grade steel ball running on a number of smaller support balls housed in a cup.
Ball transfer units have some different types that Cup Rollers, Heavy Load Rollers, Pot Rollers, Spring Loaded Rollers and Special Pot Rollers.
All carbon steel ball transfers are prelubricated and sealed, thus not requiring further maintenance. Most units have a drain hole in the bottom of the unit to expel dirt and moisture.
Ceramic Ball Bearings(also called Hybrid Ceramic Ball Bearings). Bearings are rated in two distinct ways: Ball Grade and Bearing Race Grade.
Race Grade has ABEC-1, ABEC-3, ABEC-5, ABEC-7, ABEC-9(the bigger the number, the better quality bearings).
Ball Grade(short for G) has G300, G25, G10, G5, G4, G3(the smaller the number, the better quality balls). Ball grade is a rating of the individual ceramic balls, and a measurement of the roundness of the balls. This is
the most important rating of a bearing. Mentime, race quality, grease, seal performance &...
Hub gears or internal-gear hubs are sophisticated gear systems commonly used on bicycles.
Hub gear systems generally have a long and largely maintenance-free life though some are not suitable for high-stress use in competitions or hilly, off-road conditions.
Better commuter or urban cycles such as Dutch bicycles commonly have 7-speed gear-hubs with 8-speed systems becoming increasingly available. Older or lesser cost utility bicycles often use 3-speed gear-hubs, e.g. the public bicycle rental programmes in Paris, Montreal, Lyon, London, and Washington, DC. Many folding bicycl...
The headset is the set of components on a bicycle that provides a rotatable interface between the bicycle fork and the bicycle frame itself.
The short tube through which the steerer of the fork passes is called the head tube.
A typical headset consists of two cups that are pressed into the top and bottom of the headtube.
Inside the two cups are bearings which provide a low friction contact between the bearing cup and the steerer.
Bicycle Headsets types have:
1) Threaded type
2) Threadless type
3) Intergrated type
4) Internal type.
