SNR Industry 34 Lubrication and maintenance SNR Ball Bearing Units SNR ball bearing units are filled with the required amount of grease at the factory. Thus additional lubrication during assembly is not necessary. Relubrication is not necessary for normal operating conditions. Under severe conditions, such as continuous operation at high speeds, high temperatures (above +70 °C operating temperature), heavy loads, or very humid or dirty surroundings, regular relubrication is necessary. Relubrication is dependent on the insert size. Relubrication should be performed during operation (rotating insert under operating temperature). Press the suitable grease into the unit until a fresh collar of grease is formed on the seals. Caution: The old grease must be allowed to emerge without hindrance. Relubrication system Grey cast iron housings are equipped with a lubrication groove within the spherical bore. The inserts have 4 lubrication holes in the outer ring which are arranged offset. Because of the arrangement of the lubrication holes, SNR inserts can be mounted in nearly all housings with lubrication groove and then be relubricated.
