{"product_id":"bartell-21788-oil-seal-oem-replacement-part","title":"Bartell 21788 Oil Seal - OEM Replacement Part","description":"\u003cp\u003eAn oil seal keeps lubricant contained within rotating shaft assemblies while blocking contaminants like dust, water, and debris from entering, making it a critical maintenance component in walk behind power trowels that operate in demanding concrete finishing environments. When an oil seal fails or shows signs of wear, technicians will typically notice oil leakage around the shaft, increased contamination of the gear oil, or accelerated wear of adjacent bearing surfaces. Replacing a worn or damaged oil seal promptly prevents costly secondary damage to gearbox internals and keeps the machine running at full efficiency.\u003c\/p\u003e\n\n\u003cp\u003eThis part is designed for use in walk behind trowel applications where the drive system is subjected to continuous rotational stress, vibration, and exposure to slurry and grit. As a direct OEM replacement, it matches the exact dimensions, lip profile, and material specification of the original factory-installed seal, ensuring a proper fit and reliable service life without modification.\u003c\/p\u003e\n\n\u003cp\u003eCompatible models include:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eBartell BC436\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWhen servicing, always clean the shaft and housing bore thoroughly before installation, inspect the seating surface for scoring or corrosion, and apply a light film of clean gear oil to the seal lip prior to pressing it into place. This helps prevent dry-start damage to the seal during initial run-in.\u003c\/p\u003e\n\n\u003cp\u003eGenuine Bartell Global OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Bartell","offers":[{"title":"Default Title","offer_id":43412763541552,"sku":"21788","price":53.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/21788.jpg?v=1784314285","url":"https:\/\/cce-industries.com\/products\/bartell-21788-oil-seal-oem-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
