The DBH 5226Sil is a radial shaft seal that keeps lubricant inside a housing while blocking dust, water and other contaminants from reaching the bearing area. Its three mounting dimensions are a 48 mm shaft, a 65 mm bore and a 10 mm height, and it carries the Lx design. Sizes like this show up often in gearboxes, pumps and power transmission assemblies, so it is a part many maintenance teams keep on their reference list.
How the seal works: the lip rides against the rotating shaft while the outer case stays press-fitted in the housing bore. That split between a moving contact and a static one is what holds oil or grease in and keeps outside debris out. Because the lip is the working surface, it wears over time; once it stiffens, tears or stops flexing, leaks and contamination follow.
Where it is found: gearboxes, centrifugal pumps, electric motors, rollers and other transmission equipment, plus agricultural machines, conveyors and process lines where a shaft turns inside a housing. A seal never operates in isolation. Bearings, bushings and the lubricant itself all influence how long it lasts, and shaft condition and surrounding cleanliness matter just as much. Inspecting it whenever the equipment is opened up is good practice.
Selecting and installing: confirm shaft 48 mm, bore 65 mm and height 10 mm, and check that the cavity accepts the 10 mm section without distorting the lip. The sealing track should be smooth, free of splines, burrs or scoring, and within the hardness and roughness the application calls for; a marked shaft will not let a new lip seal properly. Coat the lip with the same oil or grease used in service, set the seal square in the bore, and drive it with a tube or press that contacts the outer edge only, never the lip. Remove any burrs from the housing first.
Finding an equivalent: send the complete part number, the three dimensions, and a photo or the old seal if available. Details about the equipment it sits in and the lubricant in use also help. With that information we can review options in the DBH line or from other brands we supply, keeping the mounting dimensions unchanged so neither shaft nor housing needs rework.
Quotes: if you already have 5226Sil, message us on WhatsApp with the number and we will prepare the quote. We can also advise on the lubricant and the bearings that share the same assembly. Send either the part number or the measurements and we will come back with the option that suits your machine.

Frequently asked questions
- What size is the DBH 5226Sil oil seal?
- It fits a 48 mm shaft in a 65 mm housing bore with a 10 mm height, and it uses the Lx design. Measure all three points on the equipment before ordering, since a small deviation is enough to prevent a correct fit.
- What tells me the seal is due for replacement?
- Look for lubricant escaping near the shaft, dirt working its way in, a lip that has gone hard, cracked or misshapen, and looseness or noise from the adjacent bearing. If the shaft shows wear on the sealing track, check it before pressing in a replacement.
- Can you source an equivalent?
- Yes. Send the 5226Sil number or the shaft, bore and height measurements on WhatsApp and we will check alternatives among the brands we carry. A photo or the removed seal helps confirm the design and lip style.
