2. Lubricants2.1 Global StandardFor working under normal operating conditions / influences we recommend thelubricants with the following minimum standard and minimum specification:Table 2.1 Lubricant standardLubricant DIN indication DIN number NoticeGrease KP 2 – K 51502 or 51825 Lithium soapAttention!Oil CLP32 – 100 51517 Part 3 ISO VG 32-68Lubricants with solid particle additives like MoS 2 , graphite, PTFE etc. are generally notappropriate for THK LM systems.

Whenordering LM Guides please specify the mounting orientation and the angle θ. If an oillubrication system is used, the lubrication passages may have to be changed. Inaddition, the end caps are equipped inside with a special seal.Table 2.3a Installation orientationsHorizontalVerticalWall mountReverse horizontal(Symbol: H)(Symbol: V)(Symbol: K)(Symbol: R)Vertical slantWall mount slantReverse vertical slantReverse wall mount(Symbol: HV)(Symbol: HK)(Symbol: RV)slant (Symbol: RK)θθθθθ = ( °)θ = ( °)θ = ( °)θ = ( °)© THK GmbH 5
