Our Product Capability
Slewing Bearing quality mainly depends on materials (ring material, rolling elements, seal and lubricant), processing
(machining) accuracy, flatness and assembly. To well control those characters and provide high quality stable slewing
bearing is what TSN's strong points
MATERIALS:
• inner ring and out ring use 50Mn or 42CrMo which have higher performance relatively and complied with EN10083.
• Material for rolling elements are maded of high chromium steel, which complies withs ISO 683-17.
• The sealing material used in TSN- slewing bearing is grease/oil resistant and manufactured from nitrile
rubber, and fluorine rubber etc. The seals are produced in accordance with HG/T 2811 (Material for Lip Type Seal Ring
of Slewing Shaft).
• Incoming inspections for every batch to control the materials.
TSN SLEWING BEARING PERFORMANCE:
• Operating temperature: The normal working temperature of the slewing rings ranges from -20°C up to
+70°C. Lower or higher temperatures are possible but require special design provisions by our Engineering
Department. The working temperature can be extended from -40°C up to +200°C.
• Service life: Slewing bearing service life is highly impacted by installation, working condition, environment,
load, rotational speed, precision of support structure, lubricating and maintenance…TSN- slewing bearing usually can
be used approximately around 6000h~10000h in normal conditions.
