How are grease seals measured?

You’ll need a precision caliper to measure the hub bore to the nearest thousandth – to three decimal places such as 1.234. The 10-19 seal has an outer diameter of 2.565-inches. Next you’ll need to measure your spindle at the point where the grease seal rides.

How do you read oil seal numbers?

How to measure oil seals

1. Metric Oil Seals.
2. Imperial Oil Seals.
3. (remember the first number is always the outside diameter)
4. 137 62 25 = 5/8″ inside x 1.3/8″ outside x 1/4″ wide.
5. 187 125 25 = 1.1/4″ inside x 1.7/8″ outside x 1/4″ wide.
6. 150 250 37 = 1.1/2″ x inside 2.1/2″ x outside 3/8″ wide.

What does TC mean on seals?

Static seal and dynamic seal (usual reciprocating motion) seal is called the oil seal. The representative form of the oil seal is the TC oil seal, which is a rubber completely covered double-lip oil seal with a self-tightening spring. Generally speaking, the oil seal often refers to this TC skeleton oil seal.

How do you specify an oil seal?

There are nine factors that designers and maintenance engineers must evaluate when oil seals are specified:

1. Shaft Speed.
2. Temperature.
3. Pressure.
4. Shaft Hardness.
5. Shaft Surface Finish.
6. Concentricity.
7. Shaft and Bore Tolerances.
8. Runout.

How do you measure a rotary shaft seal?

On the back side of the “seal head” (the end which fits towards the “spring”), measure the inside diameter. This will determine the seal size diameter – which is either the shaft size or the sleeve size that the seal fits over. The front side of the seal usually has a black carbon face.

How do you measure a mechanical seal?

How Are They Measured?

1. Remove the seal face from the spring and assess its inside diameter. This will determine the shaft or the sleeve size.
2. Next, determine the length of the spring once separated from the seal face.
3. Measure the outside diameter, the inside diameter, and thickness of the stationary seat.

What does SC mean on oil seal?

Rotary seals / Standard shaft seals The SC profile is a shaft seal composed of a single metal cage with a rubber coating and a primary sealing lip with integrated spring.

What are the four factors that determine the selection of an oil seal?

There are nine factors that designers and maintenance engineers must evaluate when oil seals are specified:

• Shaft Speed.
• Temperature.
• Pressure.
• Shaft Hardness.
• Shaft Surface Finish.
• Concentricity.
• Shaft and Bore Tolerances.
• Runout.

Are oil seals directional?

Seals come in a variety of configurations, double lip, single lip, spring tensioned, Viton, Teflon, etc but did you know they can also be directional! You can get bi-directional, clockwise and anticlockwise. The best ones are directional.

What is a seal in engineering?

A mechanical seal is a device that helps join systems or mechanisms together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets.

What is SC oil?

SC oil was developed for engines made from 1964 to 1967, SD for those made from 1968 to 1971, SE from 1972 to 1979, SF from 1980 to 1989, SG from 1989 to 1993, and SH from 1994 to present. Oils with higher service classifications may be substituted for oils with lower classifications, but not vice versa.

What is the first thing to consider when selecting seals?

LIQUID. Identifying the exact liquid being handled is the first step in the seal selection process. Seal material must be able to withstand the fluid being processed. All seal materials must be chemically compatible with the fluid, or there is an increased risk of seal failure.

Which factor is important in sealing?

The area occupied with the lubricating film is called the sealing gap. Both the temperature of the lubricant under the lip as well as the temperature in the tip of the lip seal are important to the seal’s lifetime and reliability.

Which way round does a seal go?

A quick rule for seals: Lip facing in to keep lubricant in, lip facing out to keep dirt out. You probably want to keep dirt out. John is spot on can I add a little more. the bearings are rubber sealed so no lubricant on the seal so a dab of grease on the shaft before fitting the seal.

What direction do oil seals go?

The seal must be installed at a 90°, or perpendicularly, to both the shaft and housing bore. This is an issue in cases where the housing does not have a counterbore or shoulder the seal can seat up against.

What is the selection criteria for seals?

Criteria for seal selection

• Fluid pressure range, the range of operating fluid system pressure, as well as frequency and severity of pressure peaks.
• Temperature range, the range of the fluid and cylinder assembly, both when operating and at rest.
• Speed,
• Fluid media,
• Hardware dimensions,
• Application of the cylinder,
