These two men are thus responsible for modern roller skate and skateboard wheels, as well as the ball bearing race inclusion in velocipedes—later to become motorbikes and automobiles. This was arguably the most important advance in the realistic use of roller skates as a pleasurable pastime.
Skateboarding, quad roller skates: Predecessor: Powell Corporation (2005) [1] Founded: 1978; 47 years ago () Founder: George Powell and Stacy Peralta: Successor: Powell Corporation (1991) Products: Skateboard decks, skateboard wheels, quad roller skate wheels, bearings and accessories: Website: powell-peralta.com
Ball bearings are placed in wheels and allow them to roll. Typically, 7mm bearings are used on quad artistic skates, but 8mm bearings can be used on certain plates that have an 8mm axle. Most inline skates use 8mm bearings. The ABEC rating determines the tolerances in the bearing; [12] the higher the ABEC rating, the more tolerance. Steel ball ...
Similar ball bearings were subsequently adopted for use on roller skates. [35] Ball bearings in skates - Richardson 1884. In 1884, two US patents claiming the use of ball bearings in roller skates were issued one after the other. George Burton filed on August 17, 1883, and was granted a patent on November 11, 1884. [41]
In 1937, Frantz entered the conveyor wheel and semi-precision ball bearing business leveraging its experience producing roller skate wheels. During World War II, millions of conveyor wheels and bearings were produced to supply conveyor manufacturers with component products to support the war effort and this established Frantz as a major ...

Henley grew his business operation from a small outbuilding at the rear of his parents' home at 309 N 14th Street, to a large modern factory which he built on North 16th Street, employing over 300 people.
Lower graded bearings are intended for the vast majority of applications such as vehicles, mechanical hobbies, roller skates, skateboards, fishing reels and industrial machinery. High ABEC rated bearings allow optimal performance of critical applications requiring very high revolutions per minute and smooth operation.
Bearing lubrication is usually either light oil or grease. Synthetic types last longer before breaking down. Grease assists in holding dirt away, and stays in the bearing longer, reducing maintenance and increasing bearing life. The lifetime of bearings used for outdoor speed skating is often quite limited due to damage caused by dirt ingress.
