Simrit 16x26x7/9.5 Premium Rotary Shaft Oil Seal

Technical Specifications & Applications of Simrit 16x26x7/9.5 Seal

The Simrit 16x26x7/9.5 Premium Rotary Shaft Oil Seal is engineered for rigorous sealing performance in demanding environments. It is a radial / rotary shaft seal (oil seal / simmerring), crafted to secure rotating shafts (16 mm inner diameter) against lubricant leakage and contamination ingress while fitting into a bore of 26 mm. The profile height is effectively 7 mm with an optional extended profile segment of 9.5 mm for enhanced sealing configurations.

Key Features & Benefits

• Optimal dimensions: 16x26 inner-outer diameters, profile depth 7 / 9.5 mm

• Premium sealing lip design: the primary lip ensures a tight seal, while the secondary lip (if present) acts as a dust / debris shield

• High-quality materials: standard variant uses NBR (nitrile rubber) or other elastomers demanded by application (possible FKM, HNBR, etc.)

• Spring-energized lip: ensures consistent contact pressure and compensation for wear over time

• Resistance to oils and greases: excellent behavior under exposure to petroleum-based lubricants

• Suitability for industrial & automotive use: designed for motors, pumps, gearboxes, rotating machinery

• Exceptional durability & leak prevention: tight contact with the shaft prevents lubricant loss and ingress of contaminants

Technical Data (Typical / Depending on Variant)

• Inner diameter (ID / shaft): 16 mm

• Outer diameter (OD / housing): 26 mm

• Profile height / width: 7 mm standard, extended 9.5 mm in certain designs

• Lip type: single lip or dual / double lip (with dust-lip)

• Material options: NBR, FKM, HNBR or other advanced elastomers depending on media and temperature

• Operating conditions: suitable for moderate rotational speeds, thermal ranges aligned with elastomer properties, and typical shaft sealing pressures

• Installation notes: ensure correct tolerances (shaft, bore) and clean mounting area for optimal seal performance

Applications & Use Cases

This seal is ideal for installations where a rotary shaft oil seal 16x26x7 (or 16x26x7/9.5 variant) is required — e.g. in pumps, gearboxes, motors, drives, rotating shafts in industrial machinery, automotive assemblies, or other mechanical systems. Because “rotary shaft seal,” “oil seal 16x26x7,” “simmerring 16x26x7/9.5,” “premium rotary shaft seal,” and “Simrit oil seal” are common search terms in English, embedding them in this description augments findability.

FAQ (Frequently Asked Questions)

Q1: What is the main function of Simrit 16x26x7/9.5 rotary shaft oil seal?
The seal prevents lubricant leakage along the rotating shaft and keeps out dirt, dust, and external contaminants. It ensures reliable sealing performance in rotating assemblies.

Q2: When to use the 9.5 mm profile variant vs the 7 mm version?
The 9.5 mm variant offers an extended lip or additional sealing feature (e.g. secondary dust lip) suited for harsher environments or higher contamination levels, provided there is space in the housing.

Q3: What materials are available and how to choose?
Standard material is NBR (nitrile rubber), due to its balance of cost and oil resistance. For more extreme temperatures or chemical exposure, FKM, HNBR, or other elastomers may be used based on your specifications.

Q4: What tolerances are critical for successful sealing?
Proper shaft finish, diameter tolerances, bore tolerances, and surface roughness are essential. Incorrect tolerances or surface defects can compromise sealing integrity.

Q5: What industries or machines commonly use this seal size?
Common in industrial machinery, motors, gearboxes, pumps, and some automotive systems. Anywhere a 16 mm shaft with a 26 mm bore requires sealing.
