Product Description

MAGNUM 57D – 63mm Figure Wheel Part Number: STRUMAG57-63 Hardness: Yellow 57D Diameter: 63mm Compound: MonoCompound Elastomeric ThermoPlastiche Formula

The Magnum 57D Wheels are the Medium Hard Wheels of the Standard Series of Figure Wheels. The Magnum is the least expensive, high quality wheel, which is used on many types of skating surfaces. The Magnum Figure Wheels are used for entry and mid level Figure Skaters. Roll-Line has developed this wheel giving it properties that provide great roll with just the right amount of grip for figures. Compulsory Figures are high precision exercises. The feet transmit the impulses to the skating boot and thus to the steering (for the direction) and finally to the wheel (for contact with the skating surface). The Roll-Line Magnum (57D) is a Medium - Profile, durable wheel which is Strong, Light, and with extremely Close Tolerances for Roundness, Trueness, and for the Cage where the Bearings and Spacers are mounted. The Roll-Line Magnum is a MonoCompound Elastomeric ThermoPlastiche wheel, which is produced utilizing an injection system. The 57D provides a moderate grip in the wheel material and is for a skating surface with reasonably good grip. The wheel color identifies which hardness the wheel is. Yellow: 57D.

The softer the wheel, or lower Shore “D” hardness number, the more the grip and slightly less roll. The harder the wheel, or higher Shore “D” number, the more the roll, with slightly less grip.

Magnum Figure Wheels are only available for purchase in sets of 8, as normal.

It is almost always recommended to use spacers in the wheels, when using standard 7mm bearings. Long ago, before the use of Lock Nuts (the nuts that have the Nylon Plastic inserts) to hold the wheels on the axles, Jam Nuts were used, but when the spacer was not as wide as the web of the wheel, or the wheel was not machined accurately, the bearings would lock up, the nut had to be tight, and could not be “backed-off”. This method, of locking the Axle Nut down, did promote proper bearing alignment and did increase the diameter of the axle from 7mm to approximately 14mm, because everything was locked down, which also saved the problems of bent axles. Today we do use Lock Nuts. It is still very advisable to lock everything down (especially for FreeStyle, Jam, and Roller Derby Skaters). Roll-Line does provide Spacers for Roll-Line Wheels with each pair of Frames or they can be purchased separately. Properly locking the Wheels down when using standard bearing types, will also promote longer bearing life. The new Roll-Line 7mm MicroBearing System , provides an absolutely Incredible ROLL (significantly more roll than even the old Snyder Super Fafnir bearings, which used to be the best). The Roll-Line MicroBearing System fits ONLY Roll-Line Frames and DO NOT Require or Use Spacers between the bearings. These MicroBearings are mounted like standard bearings with the shields to the Outside.
