76 x 51 x 2mm Ball Bearing Butt Hinge Grade 316 - SSS

Ball bearing hinges are supplied ready lubricated by the manufacturer to ensure smooth operation of hinge leaves when fitted to doors. In some cases after installation there will be signs to varying degrees of clear oil seepage. If left for a period of time and particularly in high usage areas such as toilets the oil will combine with atmospheric dust and darken in colour. To avoid the mixture of dust and oil acting as a grinding paste on the ball bearings, which accelerates wear, it is recommended that the product be cleaned periodically. How often the product is cleaned is based on the environment in which it is fitted combined with the assessment of the maintenance officer. It is also advised that the product is lubricated at 25,000 cycle intervals to maintain optimum efficiency of the hinge. However a simple monthly cleaning programme will be sufficient for all low usage areas such as cupboard doors and a fortnightly program is advised for high usage areas such as toilets. This will ensure your products lifespan is maximised and also visually acceptable to the environment in which is fitted.
