PARTS OF A SKATEBOARD

Most decks are constructed with a six to seven-ply cross-laminated maple wood. Some of them have special materials that help to keep the deck from breaking: such as fiberglass, bamboo, resin, Kevlar, carbon fiber, aluminum, and plastic. Some decks made from maple ply are dyed to create various different coloured ply.

Grip tape, when applied to the top surface of a skateboard, gives a skater's feet grip on the deck. It is most often black but can come in a variety of colors including clear, allowing the top of the deck to be decorated. It has an adhesive back and a sandpaper-like top.

Attached to the deck are two metal (usually aluminum alloy) trucks, which connect to the wheels and deck. The trucks are further composed of two parts. The top part of the truck is screwed to the deck and is called the baseplate, and beneath it is the hanger. The axle runs through the hanger. Between the baseplate and the hanger are bushings, they provide the cushion mechanism for turning the skateboard.

The wheels of a skateboard, ussually made of polyurethane, come in many differant shapes and sizes to suit different types of skating. Modern street skaters perfer smaller wheels ussually (51-54mm), As small wheels with lighter trucks make flip tricks much easier by keeping the center of gravity of the skateboard closer to the deck.

Each skateboard wheel is mounted on its axle via two bearings. With few exceptions, the bearings are the industrial standard "608" size, with a bore of 8 mm, an outer diameter of 22 mm, and a width of 7 mm. These are usually made of steel, though silicon nitride, a high-tech ceramic, is sometimes used. Many skateboard bearings are graded according to the ABEC scale. The scale starts with ABEC1 as the lowest, 3, 5, 7, 9. Each bearing usually contains 7 steel or ceramic ball bearings, although other configurations are used as well.

Mounting hardware is a set of eight 10-32 UNC bolts, usually an Allen or Phillips head, and matching nylon locknuts. They are used to attach the trucks to the board. Some sets have one different colored bolt to show which side is the nose of the skateboard.
