Frequently Asked Questions
Q: What are the specifications for JIC-S301013?
A: JIC-S301013 is a 2.5 inch bore by 5 inch rod seal kit for loader clam cylinders. The kit is engineered for cylinder model S301000 and fits equipment models 821 and 821B. The seal code I-U-10 identifies the specific seal type and compound engineered for these applications. This is a mid-range bore size suitable for moderate to heavy clamping loads.
Q: Does JIC-S301013 fit both model 821 and 821B loader clams?
A: Yes. JIC-S301013 fits both model 821 and model 821B loader clams. Both models use the same cylinder S301000 with identical 2.5 inch bore and 5 inch rod dimensions. The 821 and 821B designations represent standard and updated production variants. A single JIC-S301013 kit works for both variants and any cylinder serial within the S301000 range.
Q: What is the cylinder model S301000 and how do I confirm compatibility?
A: S301000 is the cylinder model number for 821 and 821B loader clams. To confirm compatibility, check your equipment documentation or measure the cylinder bore (should be 2.5 inches) and rod (should be 5 inches). If your loader is model 821 or 821B and the cylinder is S301000, JIC-S301013 is the correct seal kit. Provide your loader serial number if you need verification.
Q: How does the 2.5 inch bore compare to other seal kits for loader clams?
A: The 2.5 inch bore on JIC-S301013 represents a mid-size cylinder suitable for moderate to heavy clamping applications. Smaller bore kits (like 2 inch) are used in lighter duty clamps, while 3 inch and larger bores handle extreme loads. JIC-S301013 provides a balance of force and precision for standard loader clam service. Verify your cylinder bore matches exactly before ordering.
Q: What does the I-U-10 designation mean for JIC-S301013?
A: The I-U-10 code identifies the specific seal type, material compound, and pressure rating engineered for cylinder S301000. This designation ensures the seals perform correctly under the pressure and temperature conditions of 821 and 821B loader clam service. When cross-referencing to equivalent or OEM part numbers, include the I-U-10 code to ensure you receive the correct seal type.
