heat boiler bearing temperature

SKF provides tips on troubleshooting bearing temperatures

Mar 12, 2014 · The average setting for a gas-powered hot water boiler is 180°F. This provides the appropriate level needed for most cold weather temperatures. If you can raise the temperature manually, do not set it any higher than 210°F (which is often the limit), and try to remain down at 190°F

» Whats normal:The role of temperature in bearing

Dec 07, 2010 · Induction heaters shut off at 250F, unless you tell it to go higher. As small as that bearing is, you need to heat to at least 250, you'll need all the slack you can get to avoid it grabbing halfway on. Toaster oven would be good. Set temp to 250, wrap bearing in foil, stick it in when the oven reaches temp, and give it 15 mins or so. Work fast.

Heating a bearing - Practical Machinist

Normally a bearing temperature of 80 to 90 °C (144 to 162 °F) above that of the shaft is sufficient for mounting. Never heat a bearing to a temperature greater than 125 °C (257 °F), unless otherwise specified. Extreme heat can cause the material to change

Temperature limits | SKF

Normally a bearing temperature of 80 to 90 °C (144 to 162 °F) above that of the shaft is sufficient for mounting. Never heat a bearing to a temperature greater than 125 °C (257 °F), because the material may change metallurgically and produce alterations in diameter or hardness.

Heating bearings

The permissible operating temperature for NBR seals is 40 to +100 °C (40 to +210 °F). Temperatures up to 120 °C (250 °F) can be tolerated for brief periods. Typically, temperature peaks are at the seal lip. Lubricants. Temperature limits for the greases used in sealed SKF self-aligning ball bearings are provided in table 1. For temperature limits of other SKF greases, refer to Selecting a suitable SKF grease.

Thermal mounting of rolling bearings

Feb 15, 1998 · Depending on the application, normal bearing operating temperatures in pumps range from 100°F to 180°F, with most running between 140°F and 160°F. Although grease is used in some vertical pumps, oil is the preferred lubricant in the majority of pump applications. Standard bearing oils in pumps remain effective to approximately 180°F.
