QHow to CLEAN AND TAKE CARE OF YOUR BEARINGS?

AAs an essential part of your skates’ performance, your bearings have to be closely looked after. You don’t always necessarily have to dismantle them. But if this is the only option left, here are a couple of tips to do your best. Try to avoid dismantling your bearings so far as possible. Firstly: You don’t necessarily have to dismantle your bearings at each cleaning. As far as possible, avoid doing so as it is a painful operation for the equipment: loss in waterproof enclosure, distortion of the caps and balls – most of the time, the gain isn’t worth the potential risks. The less mistreated the more waterproof. Do not dismantle or only if necessary (water, sand, screeching…) A light and efficient maintenance Just like for cars or machines the maintenance of which must be regular. Check your equipment every 5 to 10 outings, or according to the intensity of your practice and to the weather. Start with: Taking the wheels off of the frame, Cleaning the surface of the bearings, without taking them off of the wheels, with a toothbrush, kitchen paper or an air gun, Making circles on the surface to take off the film of dust, Using the occasion to give the frame a quick wipe and brush.

QWhat is REXROTH VANE PUMP?

AHydraulic pumps of type PVV are vane pumps with constant displacement. The rotor running in a stator ring is located on the tooth profile of the drive shaft. The slots of the rotor accommodate the vanes which are pressed against the internal surfaces of the stator ring by the centrifugal force upon rotation of the rotor. The displacer chambers are laterally sealed by the control plates. Due to the double-eccentric design of the stator ring, there are in each case two pressure chambers opposite of two suction chambers, which provides for hydraulic unloading of the shaft. So it only has to transmit the torque. The vanes are partially unloaded upon passage through the suction range. This unloading has a wear-reducing effect and ensures high efficiency. By simply removing the cover, the pump insert (consisting of rotor, vane, stator ring and control plates) can be removed without the need of removing the housing from the pump carrier. This allows for fast maintenance and repair of the pump.

QWhat is SKF CYLINDRICAL ROLLER BEARINGS?

ASKF cylindrical roller bearings are available in many designs, series and sizes. The major design differences between the bearings presented in this section are in: the number of roller rows (one, two or four) the type of cage (with, without or special designs) Bearings with a cage can accommodate heavy radial loads, rapid accelerations and high speeds. Full complement bearings (without a cage) incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds. SKF high-capacity cylindrical roller bearings combine the high load carrying capacity of a full complement bearing with the high speed capability of a bearing with cage. the configuration of the inner and outer ring flanges (position and number of guide flanges)

QWhat is SKF DEEP GROOVE BALL BEARINGS?

ADeep groove ball bearings are particularly versatile. They are suitable for high and very high speeds, accommodate radial and axial loads in both directions and require little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from SKF in many designs, variants and sizes. In addition to the bearings presented in this section, deep groove ball bearings for special applications are shown under Engineered products. These bearings include: Sensor bearing units High temperature bearings and bearing units Bearings with Solid Oil INSOCOAT bearings Hybrid bearings NoWear coated bearings
