API 612 2014版
10.4 Bearing Housing
10.4.1 Bearing housings for pressure-lubricated hydrodynamic bearings shall be arranged to minimize foaming. The drain system shall be adequate to maintain the oil and foam level below shaft end seals. The rise in oil temperature through the bearing and housings shall not exceed 30 °C (50 °F) under the most adverse specified operating conditions. The bearing outlet oil temperature shall not exceed 80 °C (180 °F). When the inlet oil temperature exceeds 50 °C (120 °F), special consideration shall be given to bearing design, oil flow, and allowable temperature rise. Oil outlets from flooded thrust bearings shall be tangential and in the upper half of the control ring or, if control rings are not used, in the thrust-bearing cartridge.

回油温度不应超过80度

API STD 617-2014:
4.9.1.3 As a design criteria, bearing metal temperatures shall not exceed 100 °C (212 °F) at specified operating conditions with a maximum inlet oil temperature of 50 °C (120 °F). Suppliers shall provide bearing temperature alarm and shutdown limits.

API STD 618-2007:
6.14.2.1.1 For compressors 150 kW (200 hp) and above, the frame lubrication system shall be a pressurized system. Splash lubrication systems may be used on horizontal compressors of 150 kW (200 hp), or less, with rolling element bearings. The crankcase oil temperature shall not exceed 70ºC (160ºF) for pressurized oil systems and 80ºC (180ºF) for splash systems. Cooling coils shall not be used in crankcases or oil reservoirs.

API STD 619-2010:
5.9.3 The rise in oil temperature through the bearing and housings shall not exceed 30 K (50 °F) under the most adverse specified operating conditions. The bearing outlet oil temperature shall not exceed 80 °C (180 °F). If the inlet oil temperature exceeds 50 °C (120 °F), special consideration shall be given to bearing design, oil flow and allowable temperature rise. In this case, outlet oil temperature may exceed 80 °C (180 °F).
